Hi there,
thanks for your reply. All that you mention checks out fine. perhaps I
wasn't clear in my original post or I misunderstand what you are getting at.
IP forwarding is working fine. I've setup PC's on the hub with 192.168.1.1
as their gateway. when i pull up a browser and request
http://www.redhat.com the linux box sees this and automagically dials the
ISP and the page comes up on the broser about 45secs later.
what doesn't work is dialing up from the remote sites to the same modem. It
verifies my password with PAP and assigns me the IP address just fine. but
then when I try to telnet or ftp to it I get no response.
any more suggestions? I haven't looked at the proxy arp thing yet but will
right away. It doesn't sound much like something that would keep me from
doing what I'm trying to do though. I will look though.
thanks,
rob
