Make two virtual ethernet interface

[wifi75]

Hello everybody,
i created 2 vm's, one is openWRT and the other is pfsense.
OpenWRT has a physical card assigned, which will be my PPPOE wan, or then need to pass the entire traffic directly to my Pfsense wan card.
How should I proceed to create 2 virtual ethernet cards and bridge them together?
or maybe I have to do it differently?
do you kindly help me?

Hi,

create a Linux Bridge (Node -> Network) and then add a vNIC to each VM with that bridge selected.
The guests then need to get some address on those vNICs to actually see and communicate with each other.
