MikroTik RB750 Voucher Setup Guide

Hey guys, welcome back to the blog! Today, we're diving deep into something super useful for anyone running a network, especially if you offer Wi-Fi to customers or guests: setting up voucher systems on your MikroTik RB750. This little powerhouse router is incredibly versatile, and with a bit of configuration, you can create a professional and controlled access system using vouchers. Whether you're setting up a hotspot in a cafe, a hotel, a co-working space, or even just want to manage internet access for visitors at home, this guide is for you. We'll break down the process step-by-step, making it easy to follow even if you're not a networking guru.

Understanding the Need for Voucher Systems

So, why bother with a voucher system in the first place? Think about it. If you offer public Wi-Fi, you need a way to manage who's connecting and for how long. Setting up voucher systems on your MikroTik RB750 allows you to create time-based or data-based access. This means you can sell internet access for a specific duration (like an hour, a day, or a week) or a certain amount of data. This is crucial for several reasons. Firstly, it helps you monetize your internet connection if it's a business. Secondly, it prevents abuse and ensures fair usage for all users. Imagine someone downloading huge files for days on end – a voucher system stops that dead in its tracks. It also provides a layer of security, as you can control access and potentially log user activity. For businesses, offering branded vouchers adds a professional touch, enhancing customer experience. It’s all about control, security, and potentially, revenue. The MikroTik RB750, being a popular and cost-effective router, is a fantastic platform to implement these functionalities without breaking the bank. It's capable of handling the processing needed for user management and authentication, making it a go-to choice for many small to medium-sized network setups. This flexibility is what makes MikroTik devices so loved in the networking community; they offer enterprise-level features at a much more accessible price point.

Prerequisites: What You'll Need

Before we jump into the juicy configuration part, let's make sure you've got everything you need ready to go. Setting up voucher systems on your MikroTik RB750 requires a few key things. First and foremost, you'll need your MikroTik RB750 router itself, obviously! Make sure it's running a relatively recent version of RouterOS, as some features or ease-of-use improvements might be specific to certain versions. You can check and update your RouterOS via WinBox or WebFig. Secondly, you'll need access to your router's configuration interface. The most common and user-friendly way to do this is using WinBox, a free utility provided by MikroTik. You can download it directly from the MikroTik website. Alternatively, you can use WebFig, which is the web-based interface, accessible by typing your router's IP address into a web browser. You'll need your router's IP address, username, and password – usually found on a sticker on the router itself or set during initial setup. Thirdly, you'll need a basic understanding of IP addressing and network concepts. While I'll guide you through the steps, having a foundational knowledge will make things much smoother. We're going to be dealing with IP addresses, subnets, and potentially DHCP configurations. Finally, and this is super important, you need a plan. What kind of vouchers do you want to create? Time-based? Data-based? What will be the standard durations and data limits? Having these details sorted beforehand will save you a lot of confusion during the setup process. Think about your target users and their needs. For example, a cafe might offer 1-hour vouchers, while a hotel might offer 24-hour or even weekly access. Knowing these parameters will make the configuration a breeze. It’s always good practice to have a backup of your current router configuration before you start making significant changes, just in case something goes wrong and you need to revert.

Step 1: Basic Router Configuration

Alright guys, let's get our hands dirty with the actual configuration. Before we even think about vouchers, your RB750 needs to be set up correctly as a basic router. Setting up voucher systems on your MikroTik RB750 hinges on having a stable and functioning network foundation. This means your internet connection needs to be properly configured, and your local network should be ready to go. First things first, ensure your WAN (Wide Area Network) port is correctly configured to get an internet connection. This usually involves setting up DHCP client on your ether1 port if your ISP provides an IP address automatically, or manually configuring the IP address, gateway, and DNS servers if your ISP requires a static IP. Navigate to IP > DHCP Client and add a new entry for your WAN interface, or go to IP > Addresses and IP > Routes to set up a static configuration. Once your internet connection is up, you need to set up your LAN (Local Area Network). This typically involves assigning a static IP address to your router's LAN interface (e.g., ether2, ether3, etc.) and setting up a DHCP server to assign IP addresses to devices connecting to your network. Go to IP > Addresses and add an IP address for your LAN interface (e.g., 192.168.88.1/24). Then, go to IP > DHCP Server and run the DHCP Setup wizard. This wizard will guide you through assigning an IP address pool, gateway, and DNS servers for your clients. Make sure your firewall is also configured to allow necessary traffic and protect your network. A basic firewall setup includes rules to drop invalid connections and allow established/related connections. You can access this under Firewall > Filter Rules. It's crucial to have NAT (Network Address Translation) enabled so that devices on your LAN can access the internet. Go to IP > Firewall > NAT and ensure you have a masquerade rule for your WAN interface. This rule typically looks like: chain=srcnat out-interface=ether1 action=masquerade. Without this, your internal devices won't be able to reach the internet. This foundational setup ensures that all your connected devices get an IP address, can reach the internet, and are somewhat protected. Once these basics are solid, you're ready to move on to the more advanced hotspot and voucher configurations. Remember, a well-configured basic network is the bedrock upon which complex features like voucher systems are built. Don't rush this part, guys; a solid foundation prevents headaches down the line! Double-check your settings, ping external addresses, and ensure devices can browse the web before proceeding.

Step 2: Setting Up the MikroTik Hotspot

Now that our basic network is humming along, it's time to introduce the hotspot functionality. The MikroTik hotspot is the engine that will drive our voucher system, authenticating users and controlling their access. Setting up voucher systems on your MikroTik RB750 directly relies on a properly configured hotspot server. To start, navigate to IP > Hotspot. Click on the Hotspot Setup button. This wizard will guide you through the process. First, it will ask you to select the interface where the hotspot will operate. This is usually your LAN interface (e.g., bridge-local or ether2 if you haven't created a bridge). Choose the interface that your users will connect to. Next, it will ask for an IP address for the hotspot network. It usually suggests an address from the next subnet, which is fine. It will then ask for an address pool – again, the default is usually okay. For the SSL certificate, you can choose 'none' for now if you don't have one, or select a self-signed certificate. We'll focus on functionality first. The DNS name is important; this is the domain name users will be redirected to when they try to access the internet before authenticating (e.g., hotspot.yourdomain.com). Make sure this is something you can resolve or is easily typed. For the administrative user, you can set up a default admin account for managing the hotspot. Once the setup is complete, MikroTik creates several necessary components automatically: a new interface list for the hotspot, a user manager for authentication, a simple web server for the login page, and firewall rules to redirect users. You'll see a new tab called Hotspot within the IP > Hotspot menu. Click on the Servers tab within the Hotspot menu and ensure your newly created server is running. You can access the default login page by connecting a device to the designated hotspot interface and trying to open any website. You should be redirected to the MikroTik login page. This confirms your hotspot is active and ready for user authentication. The key here is that this hotspot server is what allows us to implement user accounts and, subsequently, our voucher codes. Without this active server, your voucher system won't have anything to authenticate against. It’s the core component that enables controlled access to your network. Remember to test this by connecting a device (like your phone) to the Wi-Fi network and seeing if you get prompted to log in.

Configuring User Profiles

Before we create any actual vouchers, we need to define what a voucher gives access to. This is done using User Profiles. Setting up voucher systems on your MikroTik RB750 involves defining these profiles to dictate speed limits, session times, and data limits. Head back to IP > Hotspot, and then click on the User Profiles tab. Click the '+' button to add a new profile. Give it a descriptive name, like 1-Hour-Access or 500MB-Limit. Now, let's configure the crucial settings within this profile:

• Rate Limit (Rx/Tx): This is where you set the speed limits. You can specify download (Rx) and upload (Tx) speeds in bits per second. For example, 1M/500k would limit users to 1 Mbps download and 500 Kbps upload. This is great for ensuring fair bandwidth distribution.
• Session Timeout: This defines how long a user can stay connected after they log in, even if they are inactive. Format is h:mm:ss (hours:minutes:seconds). For a 1-hour voucher, you'd set this to 1:00:00.
• Idle Timeout: This limits the time a user can be inactive before being automatically logged out. This is useful for preventing stale connections.
• Keepalive Timeout: This is less commonly changed but relates to how often the server checks if a client is still active.
• Shared Users: This setting determines how many devices can use the same username and password simultaneously. For most voucher systems, you'll want this set to 1 to ensure each voucher is used by only one user/device at a time.
• Data Limit (Bytes): This allows you to set a total data transfer limit per user session. You'll need to specify the limit in bytes. For example, 500 MB would be 524288000 bytes (500 * 1024 * 1024). This is perfect for data-capped plans.

You can create multiple profiles for different types of access. For instance, you might have a 1-Day-Unlimited profile with a longer session timeout but no data limit, and a 500MB-Limited profile with a shorter session timeout but a strict data cap. The beauty of profiles is that when you create users (vouchers), you simply assign them to a profile, and they automatically inherit all these settings. This makes managing different access tiers incredibly efficient. Think about the specific offers you want to provide your users. Do they need unlimited speed for a short period, or a slower speed for a longer duration? Do they need a data cap? Defining these profiles clearly upfront is key to a successful voucher system. Don't forget to click 'Apply' and 'OK' after configuring each profile. You can create as many profiles as you need to cater to various customer demands and pricing strategies, making your RB750 a versatile tool for managing paid Wi-Fi services.

Creating the Voucher Users

Now for the fun part – generating the actual vouchers! Setting up voucher systems on your MikroTik RB750 culminates in creating these individual user accounts. In the IP > Hotspot menu, navigate to the Users tab. Click the '+' button to add a new user. This is where you create each individual voucher:

• Server: Select the hotspot server you configured earlier (usually hotspot1).
• Name: This is the username part of your voucher. Make it unique and easy to remember or generate.
• Password: This is the password part of your voucher. You can generate a strong password or set a simple one if you prefer. Ensure it's something you can distribute.
• Profile: This is the crucial link! Select one of the User Profiles you created in the previous step (e.g., 1-Hour-Access, 500MB-Limit). This assigns all the speed limits, session timeouts, and data limits defined in that profile to this specific user.
• Limit Uptime / Limit Bytes: These are additional, specific limits you can set per user, overriding or supplementing the profile settings. You can use these if you need to create a unique voucher with slightly different parameters than any of your standard profiles. For example, you could have a 1-Hour-Access profile, but create one specific voucher user with a 1:30:00 uptime limit instead of 1:00:00.

Tips for Generating Vouchers:

• Batch Creation: While you can add users one by one, for many vouchers, consider using scripting or external tools that can generate lists of usernames and passwords and then import them or use the MikroTik API. However, for a small number, manual creation is fine.
• Naming Convention: Use a consistent naming convention. Maybe prefixes like cafe- for cafe vouchers, or sequences like user001, user002.
• Password Strength: For security, use strong, random passwords. You can generate these using online tools or scripts.
• Distribution: Decide how you'll distribute these vouchers. Will you print them? Send them via SMS? This affects how you format the username/password pair.

Once created, these username/password pairs are your actual vouchers. When a user connects to your hotspot network, they will be prompted to enter one of these combinations. Upon successful authentication, they will be granted internet access according to the profile you assigned them. It’s this user management system that transforms your MikroTik RB750 from a simple router into a sophisticated access control device. Keep a record of the vouchers you create, especially if they are for sale, so you don't lose track. Setting up voucher systems on your MikroTik RB750 is essentially about defining rules (profiles) and then creating credentials (users) that adhere to those rules. It’s straightforward once you grasp the relationship between profiles and users. Test each voucher type you create to ensure it behaves as expected. You can check the status of active users under the Active tab in the Hotspot Users list.

Step 3: Customizing the Login Page (Optional but Recommended)

While the default MikroTik hotspot login page works, it's not very professional. Setting up voucher systems on your MikroTik RB750 can be significantly enhanced by customizing the look and feel of your login page. This is where you can add your brand logo, instructions, and make it more user-friendly. Navigate to Files in WinBox. You'll see a list of files on your router. The hotspot files are typically located in a folder named hotspot. Inside this folder, you'll find HTML, CSS, and image files. You can download these files to your computer, edit them using a text editor (like Notepad++, VS Code) or an HTML editor, and then re-upload them to the router. Look for files like login.html, status.html, and logo.png. You can replace logo.png with your own company logo. Editing the HTML and CSS files allows you to change the layout, colors, fonts, and add custom messages. For instance, you can add instructions like: "Welcome to Our Free Wi-Fi! Please enter your voucher code below." or "Purchase vouchers at the front desk.". Remember to keep the form element (<form>) and the input fields (<input type="text" name="username">, <input type="password" name="password">) intact, as these are essential for the hotspot authentication to work. If you're not comfortable with HTML/CSS, you can find many tutorials online for customizing MikroTik hotspot pages. Some advanced users even create full-fledged landing pages with payment options integrated, though this is beyond the scope of a basic setup. Crucially, after uploading your modified files, you might need to clear your browser cache or use a different browser/incognito mode to see the changes, as your browser might have cached the old page. You can also test by connecting a new device or using the router's 'Ping Tools' to access the hotspot page URL. A well-customized login page not only looks good but also provides a better user experience, reinforces your brand identity, and can even guide users on how to obtain vouchers. It's a small step that makes a big difference in the perception of your service.

Monitoring and Management

Once your voucher system is up and running, you'll need to monitor its performance and manage your users. Setting up voucher systems on your MikroTik RB750 isn't a one-time setup; ongoing management is key. MikroTik provides several tools for this:

• Hotspot > Active: This tab shows you who is currently connected and authenticated. You can see their username, IP address, uptime, data transferred, and the profile they are using. From here, you can also manually disconnect users if needed.
• Hotspot > Users: This is where you manage your created user accounts (vouchers). You can add, remove, or disable users here.
• System > Leases: Under IP > DHCP Server, the Leases tab shows IP address assignments. This can help you see which IP addresses are allocated to connected devices.
• Queues: For more advanced speed management beyond basic profile limits, you can use the Queues menu (Queues > Simple Queues or Queues > Tree). This allows for more granular control over bandwidth for specific users or groups.
• Logging: Configure logging (System > Logging) to record events like user logins, logouts, and errors. This is invaluable for troubleshooting and auditing.

Regularly checking these sections will help you identify any issues, understand network usage patterns, and ensure your voucher system is operating smoothly. For instance, if you notice a particular user consuming excessive bandwidth, you can check their profile or limits. If users report problems connecting, the Active and Leases tabs are your first stop. Setting up voucher systems on your MikroTik RB750 provides a robust way to manage access, but proactive monitoring ensures it continues to serve your needs effectively. Don't forget to schedule regular checks, especially during peak hours, to ensure optimal performance and user satisfaction. Keep an eye on your router's CPU and memory usage as well via System > Resources to ensure it's not overloaded, which can happen if you have a very large number of concurrent users or complex configurations.
