I think that running NFS on a firewall is _never_ reasonable. I played a
Yes you're right, sorry my question must have sounded a bit stupid without further info. My setup is rather small-scale: while I have the computer at uni, I need NFS-access (both directions) over the local ethernet. The university has border firewalls installed, any attack would have to come from a (possibly hacked) machine inside. While I have the machine at home, I have no ethernet, and definitely need any protection I can get (ISPs are providing real internet service - in both directions, i.e. everything open). Back at uni I thought it doesn't hurt to keep the firewall setup running... And I can dialup as well while being at uni, in which case I definitely want to close NFS ports to ppp0!
A firewall with server functionality is a contradiction in itself and certainly not recommended.
True, but running firewals is better than not doing it... So, is anyone able to give a port-range which is typically used by NFS? Thanks, Volker
