I *do* run them through a firewall. I run a local ipf on every server for a) anti-spoofing b) blocking services the daemon can't be told to only serve on certain interfaces/nets. > Real firewalls inspect the portmapper protocol, learn about what > ports get registered and automatically allow sessions to the registered > ports. So what, in your opinion is an example for a "real firewall"? > NFSv4 got rid of all the SunRPC details.

NFSv4 daemon for NetBSD, anyone? > You configure firewalls to limit traffic between networks, not interfaces. In my setup, on most interfaces, each interface (vlan*) only carries one network.
