I just had exactly the same set of NFS error messages at startup. In my
case it was because I had accidentally enabled the firewall in the machine's
config, and that machine had only the default deny rule. Easily fixed.
But, it makes me think that the answer to your question might well be Yes,
the ipfw rules could be the problem.
I notice you don't have the "customary" rules
100 allow ip from any to any via lo0
200 deny ip from any to 127.0.0.0/8
I wonder if that could be the cause? I rediscovered the hard way a couple
weeks ago that these rules are normally installed by rc.firewall in addition
to any config file you specify in rc.conf, but if you manually do an ipfw
flush then reinstall your usual rules you lose these two automatic rules.
