Portmapper sits on one port, but it's redirecting the nfs connection all

The rpc services called by portmaper can be binded to specific ports, see
man pages for details. To find out what services are registered run:
I guess what I should be asking is where/how do I bind specific ports?
I can't find anything in the man pages (at least the ones I'm looking
at) to set this up. I am running the kernel based server so I may have
a harder time with all the configuration options, but I don't really know.
I opened up port 111 for the sunrpc protocol, but that's as far as I got
with the firewall.
But I'm not really sure what I am supposed to do with this:
in the /etc/defauls/nfs-kernel-server. I think this is the point where
I'm stuck. The man page for rpc.mountd mentions things like:
' --port num' but setting : RPCMOUNTDOPTS="--port 2049" fails because it
doesn't know how to handle these options/string/format. By default, it
should use 2049, but I don't think it knows that? Something doesn't,
that's for certain.
When I first started trying to use nfs, I open port 111 (sunrpc) and
then it was trying to access a port 815 (or something in the 800's) and
that didn't map to anything. And there I realized that I wasn't getting
this right at all.
