I have a temporary requirement to simulate a dedicated wide area network
which will be used to bridge four remote sites together.
Currently, the equipment for all four sites is at a single site, and I was
intending to use m0n0 with four ethernet cards to simulate the dedicated
wide area network.
After setting up the four ethernet cards with the appropriate IP addresses
and subnets, I was intending to simply add firewall rules to allow access
from each card to every other card (TCP/UDP access, no ports blocked).
Would this be the preferred approach - and is there a way to avoid having
to dedicate an additional ethernet card to the WAN interface (which I am
not intending to use)?
