This works in the sense that client requests come from the new range.
However, nfs/rpc ports are also from the new range, so the original
goal to block these ports is defied. Is there anything else apart
to the stateful filtering one can do? (which isn't an option on
the router). Can one specify the ports used by the portmapper?
