Psyche default firewalling is a bit brut force.  I would recommend using one
of the iptables scripts available on the net.  I like gShield, shorewall
gets some good press also.  As far as which ports you should open do a
google search on "common tcp ports nfs"  In the case of nfs I believe all
you need is sunrpc portmapper(111) and nfs (2049)  If you are using gShield
there is an nfs option in the gShield.conf file to open or forward nfs
ports, handles what is needed.

Subject: nfs client conflicts with iptables on my computer.


When iptables is up, my computer can't mount remote fs.The error message
is "RPC time out". After I stop it, nfs client works fun. I deleted some
rules one by one to find which rule blocked the access. The result is
the rule of 0:1023 port udp rejection. I am anxious to know which port
shall I open or how to get though the iptables normally when mount nfs
fs.
