[KLUG Members] Network config

[John Pesce]

Hi,

I used to have two private lans (192.168.2 and 192.168.3) located in
separate buildings with a firewall on each to the outside world. I've
since relocated them into the same building on a common switch with
separate VLANs. I did this because they both operate a UDP multcast
simulation and we don't want UDP packets getting on the other subnet.

Both firewalls are now redundate. My question is, how can I connect the
two subnets to be transparent for sharing a firewall and
for ssh,rlogin,etc, without allowing the UDP multicast to get through?

Would I reconfigure the second firewall to exist on both subnets with
IP_Forwarding? Would I need packet filtering?

Thanks,
John
