Connect two machines ethernet in a network

[domingoperez]

I want to connect two machine that only speaks ethernets. Between this machines there are 2 routes like is shown below:

eth wan eth

machine1 <-----> routerA <-------->routerB <-------> machine2

This machines dont speak IP and the traffic between them mus be unicast.

how can I connect this two machines?

Sounds like you need to configure transparent bridging on the routers.

If you have just those two routers then transparent bridging sounds like the easiest solution.

If you have other routers or other machines that use IP, you can setup an IP Tunnel between the two routers. It takes the packets, in whatever encapsulation, and re-encapsulates in an IP header to the other defined end point which then strips the header and forwards the traffic. Keep in mind this burns CPU on the router.
