How to Redirect Internet Traffic from Router A to Router B via Mikrotik VPN

To redirect internet traffic from Router A to Router B using a MikroTik VPN, you'll need to configure routing and VPN settings on your MikroTik device. Here's a general outline:

1. Set Up the VPN:

• Configure the VPN client on your MikroTik router to connect to Router B. This could be an L2TP, PPTP, or WireGuard VPN, depending on your setup.

• Ensure the VPN connection is active and has a valid IP address.

• Add a route in the MikroTik router to direct traffic destined for the internet through the VPN interface.
• Use the IP > Routes menu in the MikroTik interface or the command line to set the gateway as the VPN interface.

3. Mark Traffic (Optional):

• If you want to redirect only specific traffic, use IP > Firewall > Mangle to mark packets based on criteria like source IP, destination IP, or protocol.

4. NAT Configuration:

• Set up NAT (Network Address Translation) on the VPN interface to ensure that traffic is properly translated when it exits through Router B.

5. Test the Configuration:

• Verify that traffic from Router A is being routed through Router B by checking the MikroTik logs or using tools like traceroute.
