OK... 192.168.0.0 won't be seen on the network. That is your "Network Address". Like wise, 192.168.0.255 is your "Broadcast address". Give your Linux box's NIC an IP from this range: 192.168.0.1 - 192.168.0.254 We'll get back to this in a minute. > My issue is that even with > the firewall off, I can't get a connection with the other machines. > Granted this is a scenario b/c I have been trialing this on my own > network first, so I don't take down the actual NT network. > I am using the internet services DNS servers, and have assigned a > machine of mine a 192.168.0.1 address. > The ethernet on the firewall is configured with no gateway since I have > read PPP does not need one ( I tried it the other way but still no luck > ) and like I stated, the linux box is connecting fine.

Let say it's 192.168.0.2. Your NT clients should now have network information like this: IP Address: 192.168.0.50 (anything but 1 or 2) Subnet Mask: 255.255.255.0 Gateway Address: 192.168.0.2 (The linux box) DNS: As provided by your ISP > > I now know I need to masquerade the packets on the network, since they > are 192.168 addresses.

Yeah you'll need to MASQ, but lets deal with basic networking first. At this point you should be able to ping the NT client from the firewall. (Just checking, but what IP range does your ISP give out? You don't want to use the same range as them). > A "dig" either gives me "operation timed out" or "host is down".

Is this the issue? Don't worry dhcp is a good thing.
