$ host 132.64.50.50
50.50.64.132.in-addr.arpa domain name pointer ard.huji.ac.il.

in other words, a server at your university. Do you run that, or does
someone else?

i.e. it can't reach your University server using NFS protocols.

So it is running NFS.

That RH9 server, is that ard.huji.ac.il, or the RH9 box on the same
network as it?

So it looks as though you're using some PPP-based tunnel (PPTP?) over
the Internet. How is that terminated at the University end: does it end
at an official University VPN server, or is it something you've set up
on 128.139.15.95, or something else?

Can you ping ard.huji.ac.il from home? If not, are you sure all the
routing is set up properly? What happens if you try traceroute from
each end towards the other end?

What is the output of /sbin/route on all the hosts in question? Is there
a suitable route in all directions along the link you're trying to set
up?

Is there any firewall on ard.huji.ac.il?

It smells like a routing problem, firewalls, or access. But you haven't
given enough information to let us know which.
