I have spent a few days on this little mess. Seems a lot of other folks have too. As I read it and try it, when you add the third Network & NIC on a Firewall box then getting the networks to work and route tables correct is difficult. In my case the third network, DMZ~webserver doesn't work. You can ping each card but no response across the DMZ~webserver network. The solution might be an explanation of how to establish three cards on one box that sets up the networks correctly. I think it would be helpful to see a successful route table and commands for how it got that way. I'm using RH8 on all boxes & eventually IPtables.
Firewall box
eth0 external IP 206.xx.yy.128
eth0:0 Multi External IPs to follow via aliasing which sets up ok for me.
eth1 LAN 192.168.0.1 this one works? miracles do happen.
eth2 DMZ 192.168.1.1 this one doesn't work
clients
LAN etho 192.168.0.2
Webserver eth0 192.168.1.2 pings itelf but won't connect to 192.168.1.1 the gateway card on the firewall box.
I have experimented thru a switch and with a crossover cable eth2 DMZ to webserver... the NIC cards are all 905s and UP, respond well etc... but the DMZ~webserver network will not hook up...YET.
I would like it if someone could confirm that this is the right track etc. and if so... is there a hint or two on the errors, IRQ error? route isn't set up right, Hardware? NIC goes into the box in some order? ... I know this is fascinating for Net guys but for me... sheesh. Like configing a combo of 100 switches and when you get done the reward is... a lite comes on in Ohio, yawn...
thanks much and still a happy little newbie but ready to go do anything else,
