Yes, it is possible to create a hotspot on a bridge in MikroTik, which is especially useful in scenarios where you need to manage multiple interfaces as one, or when you want to apply hotspot policies to multiple physical networks or network segments at once. The process involves configuring the hotspot service to work with a bridge, which acts as a joining point for two or more network interfaces. Below are the general steps to configure a hotspot on a bridge in MikroTik:

1. Create the Bridge

First, you need to create a bridge and add the desired interfaces to it.

1. Go to Bridge > Add New (o +) to create a new bridge.
2. Give the bridge a name and configure the settings as necessary.
3. Then, in the tab Ports, add the interfaces that you want to include in the bridge by selecting them and specifying the bridge created in the previous step.

2. Configure IP Address

Assigns an IP address to the bridge. This address will be used by the hotspot server.

1. Go to IP > Addresses.
2. Add a new IP address and select the bridge as the interface.

3. Configure Hotspot Server

Now, configure the hotspot server to use the bridge.

1. Go to IP > hotspot.
2. In the Servers, Click on Hotspot Setup.
3. Select the bridge created above as the interface on which the hotspot will run.
4. Follow the instructions in the setup wizard to complete the hotspot setup, including the IP address range for clients, the IP address pool, and any other necessary settings, such as the login page, user profiles, etc.

4. Configure Firewall and NAT Rules (If necessary)

Depending on your network and security configuration, you may need to adjust your firewall and NAT rules to allow appropriate traffic through the hotspot.

• Make sure that your firewall rules allow traffic to and from the bridge on the ports used by the hotspot service.
• Configure NAT rules for address translation if necessary, especially if you are sharing an Internet connection through the hotspot.

5. Test and Verification

Finally, test the setup by connecting to the hotspot with a client device. Verify that the login page displays correctly and that you can authenticate and browse the Internet as expected.

Creating a hotspot on a bridge in MikroTik is an efficient way to manage network access for multiple interfaces or network segments through a single management point.

However, it is important to consider the security and performance implications, since traffic from all devices connected to the hotspot will pass through the bridge.
