Problem Reaching Gateway (Seperate Networks?)

[Dogma]

I'm setting up a box at a locale isp. Problem. The isp has two class c networks. The gateway (only one) exists on the original network. Originally I had "network unreachable" problems, now ping works but i get absolutely no response from the machine i'm pinging, all packets are being lost. Does anyone know how to address the gateway?

Could you post a layout of the network configuration? I'm a little confused.

Sounds like there is a gateway to the second network, that you don't know about. How does the 203.56.106.0/24 network talk to the default at 203.41.81.76? There are different networks.

When you have the missing info do this:

route add -net 203.41.81.0 netmask 255.255.255.0 gw (missing ip) dev eth0

I asked the ISP if there was and there apparently is not. I was given a solution by another person which involed (I think) addressing the hw of the gateway's NIC. This worked, however, I have since lost any record of how to do this. I unfortunately have been completely unable to contact this person. Other things to note the ISP is entirely MS based and I don't believe he himself has a great understanding of the TCP/IP fundamentals etc as the MS OS and software has handled these things for him.
I also tried to get an ip on the other network but he only has about ten left and says they are reserved (i have forgotten what for).
