You should not be running portmap and NFS on a firewall machine. You should not attempt to pass NFS or other filesharing through a firewall, except perhaps by using VPN tunneling. If this existing machine needs to do NFS to your other Linux boxes, it should be placed behind a properly hardened firewall which perhaps uses NAT to forward HTTP connections inside to it. -- -Chuck
