It sounds like you've got RH 7.1 so you can use iptables instead of ipchains and add rpc connection tracking. You'll have to patch your kernel so you might as well get the latest kernel source, get the latest netfilter patches and iptables from one of: http://netfilter.samba.org/ http://netfilter.gnumonks.org/ http://netfilter.filewatcher.org/ Then use patch-o-matic to add the rpc connection tracking capability (and any other patches you fancy) to the kernel. Build and install the kernel and insert your iptables rules. This is a lot more work than you planned I'm sure but it's the only way to get effective firewall security while allowing NIS and NFS.
