No one explained the way this should really be set up - while your setup
may work for testing, the production setup would be:
- two physically separate networks - one unprotected outside the firewall,
and one protected inside the firewall.
- one card configured with 192.168.0.1 / 255.255.255.0
- the other card configured with 192.168.1.1 / 255.255.255.0
This puts the 2 cards on 2 different subnets. All devices on the second
network would use 192.168.1.x addresses. The system then knows to route
traffic to one card or the other based on subnet. (Actually, I don't know
if that's true - that it knows automatically. I know more about Windows
than I do about Linux, and Windows *knows* - so I just assume Linux is
smarter!)
If you knew all this - forgive me. If you didn't - hope this helps.
