Hello psyche-list, I've got a couple of RH 8.0 systems on a network. On one of these, I've set up a couple of entries in /etc/exports and set up NFS. On this (server) machine, I have opened up the iptables firewall to allow incoming tcp/udp ports 111 and 2049. On another (client) system, I've also opened up the iptables firewall to allow incoming tcp/udp ports 111 and 2049. On this client, I have been able to NFS mount just fine, if I "/etc/init.d/iptables stop" first. After a lot of trial and error, I determined that the iptables line "at fault" is the one that blocks all incoming 0:1023 udp traffic. Now, I'm stuck. I'd like to leave that line in the firewall, but I would also like this machine to be able to be an NFS client. I have not yet tried any other client machines. Below is my iptables file. Any ideas? Thanks!
