How can I find out what port NFS is running on so I can let it through
my subrouter?

install nmap and port map yourself ... or netstat -a | grep nfs(d) ....

It tends to vary somewhat. portmapper is quite loose and fancy free with
port numbers, you will often find 2049 in use and others around 900 or
so. nmap is your friend here, as well as netstat and tcpdump in extreme
cases
If this becomes a problem, most nfs tools support a -p option where you
define which one you want.

rpcinfo -p <hostname> should tell you. Note that you might need to open
other ports in addition to those used by nfs itself. In particular, the
statd, lockd and mountd daemons usually use random ports, and I don't
know whether and how they can be instructed to use fixed port numbers in
Gentoo. Refer to this document for more information:

Modify /etc/conf.d/nfs to setup the ports you want to use:
OPTS_RPC_MOUNTD="-p nnnnn"
OPTS_RPC_STATD="-p mmmmm -o pppppp"
Modify /etc/sysctl.conf to set up the lockd port:
fs.nfs.nlm_udpport = xxxxxx
fs.nfs.nlm_tcpport = xxxxxx
NFS uses port 2049 as standard, portmap uses port 111
Cheers, Dave
