Hello,

I think that I might be a little ambigious. Basically I have 3 windows 
masqed PCs, on a 192.168.x.x network. There is a RH linux FW with 2 
interfaces, one on the 192.168.x.x network and one on the internet with the 
IP 216.103.x.x. From my 192.168.x.x network, I can ping 216.103.x.x, i.e the 
RH linux host. I can also telnet to 216.103.x.x from the 192.168.x.x 
network. On the 192.168.x.x, there is a web/ftp server which I have used 
ipchains to allow the internet to connect to. i.e. people from the internet 
can ftp 216.103.x.x or http://216.103.x.x and access this internally masqed 
win2000 ftp/http server. But from the 192.168.x.x. network, I cannot access 
ftp 216.103.x.x or http://216.103.x.x. But if I use its internal IP address 
from the 192.168.x.x network, I can access it locally. What should be done 
to allow my 192.168.x.x hosts to access ftp 216.103.x.x or 
http://216.103.x.x?

Thanks for all the responses!

Vernon
