[plug] DMZ with IPCop

[Daniel Pearson]

Has anyone had experience with running a DMZ with IPCop? I'm running into a
few issues, and can't seem to put my finger on what exactly is wrong.

The router has 3 interfaces, eth0 (internal lan, 192.168.100.0/24), eth1
(dmz connected by crossover, 192.168.50.1 + .2), and eth2 is the external.

Now, from the router, or any machine on the network I can ping 192.168.50.2,
however from 50.2 I cannot ping anything on the 100 network, or even the
router on the other end of the crossover cable. Also, when I edit
/etc/resolv.conf on the router and put .50.2 as its nameserver, from the
router I can then not ping anything.

As a result of such.. my DNS isn't working, as that resides on the DMZ
(debian woddy 3 default install, running bind 9, apache and postfix). Has
anyone else come across this before?
