IP forward and Firewall

Hi Mickey , Hi everybody

I am still trying to get familiar working....
I hqve qn iPAQ H3660.
I have install Familiar v0.4 and I am still stuck at the network part of the
1rst boot.

What I have ?
The host PC is a Linux Redhat 7.1 machine with a static IP.
This IP isnot behind the firewall and so the machine is directly on the
backbone of the university.
The IP I have been given for the IP is behind the firewall (no direct ftp,
the only traffic available is http and email).

What have I done ?
I have set up a PPP connection like describe in wiki PPPHowto and I tryed to
have a IP Masquerading like explained in IPMasqHowto

Making the connection (iPAQ in COM2), Linux RedHat on the host.
This pqrt is working and I am able to ssh into the ipaq.
Once log in, I can ping khumbu (khumbu.eeng.dcu.ie is my nameserver), and
familiar and other websites.

But when I do ipkg update, It seems that the iPAQ is not able to find the
route to familiar. I have :

Seems like to me that I screw up in the choice of what I should have done
for setting IP Masquerading. Any suggestions ?
