It's not actually a DSL router, but just a DSL modem capable of being hooked to 
ethernet directly.  My current hub only has 4 ports, and all 4 are in use before the 
modem arrived.  The modem does indeed to nat and uses PPPoA encapsulation for it's VPN 
portion from my system to MSN via qwest.

The modem does a DHCP for the ethernet card it is connected to, assigning it 
192.168.1.2
Should I permanently assign that address to the eth0 interface or leave it as DHCP 
assigned?

My kernal is stock redhat 7.2.  I have ipforwarding in the kernal is my assumption 
because I have ipchains and iptables as installed components also.

Was working my may down one of those last couple of days, but they loose me terribly.

I use iptables:

[root@Webby pam.d]# /sbin/iptables -nvL
Chain INPUT (policy ACCEPT 508K packets, 60M bytes)
 pkts bytes target     prot opt in     out     source               destination 
Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
 pkts bytes target     prot opt in     out     source               destination 
Chain OUTPUT (policy ACCEPT 441K packets, 46M bytes)
 pkts bytes target     prot opt in     out     source               destination

only one I want to actually serve the web is the linux server, I will be running 
misterhouse and some other services on it someday soon.

I have statically assigned them, they are currently all 192.168.0.x addresses because 
I was using a dialip modem and microsoft internet connection sharing.
