Network configuration problem.

[Erik P. Olsen]

I don't know if this is the correct list to ask. I apologise if not.

My internet access is through a router owned by my ISP. The WAN side is
a fixed address which is translated to 192.168.1.0, netmask
255.255.255.0. Fairly normal, I think. The LAN interface is 192.168.1.1
to which my server is connected via an ethernet interface. Address
192.168.1.7 is to a Linksys wireless router, address 192.168.2.0. This
is for my customers so I can hook them up to my network whenever they
visit my office. This is a fine setup for my customers. The only problem
I have and which I have not been able to solve is that I can't see the
customer machines on the network from the server but they can see the
server. To put it simple, a machine on 192.168.2.125 can ping the server
on 192.168.1.1 but I can't ping the other way.

What do I need to specify? I am happily running FC2 updated to latest
level.

netstat -rn on server yields:

I have tried to route add -net 192.168.2.0 gw 192.168.1.7 to no avail.
netstat on a customer machine gave:
