- Try root at poirot rengland]# /usr/sbin/showmount -e localhost
   If it doesnt show anything meaningful, then may be you need to
   check your configs or try running
   # exportfs -ar
- Hope you've tried `iptables -F` on both the boxes.
- Make sure, you haven't blocked portmapper access through
  TCPWrappers - check /etc/hosts.allow and /etc/hosts.deny
- And perhaps, you might want to run tcpdump on your network
  interface and look for dropped packets or so.
