I originally posted this in the 10.3 Panther Server General forum, but thought it might be more appropriate here.

‘m running Panther Server 10.3.5 on a machine with two ethernet interfaces: the built-in one (en0) and a third-party PCI NIC (en1).

I’ve set up en1 to connect to my ADSL router using the 192.168.1.0/24 network. en0 is using 10.0.2.0/24 and is attached to an Airport Extreme base station, which in turn is running DHCP and NAT to provide internet access to wireless clients.

Now from the machine running Panther Server, I can ping out to the internet and surf the web without a problem. In addition, I can ping both interfaces of the Panther Server machine from my PowerBook using AirPort. What I can’t do is access the internet from the PowerBook.

It seems that the server somehow isn’t routing the requests properly, but I’m not sure what the problem is with my setup. I have en1 listed as the first interface in the Network Preferences pane, and en0 second. I’ve set the router under en1 as the address of the ADSL modem, which I’ve also set as the DNS server. I’ve left the router and DNS fields for en0 empty. Is there any additional set-up to do?
