Routing between subnets

Hi everyone!
Having a little trouble with probably a simple task…

  • I have a mikrotik router acting as a switch with all ports bridged.
  • On ether 1 I have connected another router through it’s wan port with a pppoe connection on the 192.168.4.0 subnet.
  • On ether 4 I have connected a desktop computer in the 192.168.5.0 subnet.

I need each thing in it’s own subnet but I cannot seem to find a way to route communication between them. What do I need to setup on the mikrotik router to allow this communication?

Thanks!

You cannot route when you have all ports in a bridge. Take port 1 out of the bridge and route between the pppoe and the bridge.

Thanks!
