How to replace a LINUX firewall

Unanswered Question
Feb 6th, 2007

I have a hub site which was part of an aquisition, but is now completely trsuted. They have a linux firewall with 192.168.0.x LAN addresses, but are all 1 to 1 static natted to 10.161.0.x addresses. I need to figure out how to remove the linux fw with either a vlan or something, but be able to preserve the IP addresses at least until I can have all the devices change their IP to the correct addresses. There are a lot of apps using the natted IP addresses and not DNS. There are some using the non natted IP when accessed internally on the segment.

Can I put in a vlan with primary and secondary addresses for both old and new segments and just route it to my WAN?

I have this problem too.
