And, Yes, it will confuse the hell out of the machines. It is wrong. Find out which nic is your internal and which is your external interface, i.e. eth0 and eth1. This can be a little tricky but how I solved it was to see which one would pick up ip info from the isp's dhcp server, and then I knew it was my external nic. Hard bind the other (internal) nic to class c private ip addy, 192.168.0.1. Set up gateway address on lan machines, set up NAT and IPMASQ on your linux server, make sure you get the routing right, and you should be ready to ride... I know, easier said than done but stay at it. It will start to make sense. Post any questions here. A lot of people here have setup what you are trying to setup, and when you get it working, we can talk about firewalling, msec, tripwire, snort or any other NIDS you might fancy, and all the other fun stuff... drjung -- J.
