I have two FreeBSD 6.1 boxes one of which (IP 10.0.0.1) is an NFS server and 
the other one (IP 10.0.0.2) is, among other things, an NFS client sharing 
directories with the NFS server.
It all works correctly and I can mount_nfs all the directories from the 
server.
BUT, I'm now trying to use an IPFW firewall both on the server and on the 
client. My simple aim is to setup connections between the 10.0.0.1 server and 
the 10.0.0.2 client ** only **; no connections should be possible with other 
clients!
Now I've tried the poor documentation I could find googling with the 
keywords "freebsd ipfw nfs" to no avail, I cannot mount_nfs any share on te 
client because something goes wrong with RPC.
Concentrating on the client side (no ipfw for the moment on teh server) I 
tried the following

ipfw add 300 allow ip from 10.0.0.1 2049,111,1022 to 10.0.0.2 via fxp0 setup 
keep-state

OR
ipfw add 300 allow ip from 10.0.0.1 to 10.0.0.2  2049,111,1022 via fxp0 setup 
keep-state
  
OR
ipfw add 300 allow ip from 10.0.0.1 2049,111,1022 to me via fxp0 setup 
keep-state

OR
ipfw add 300 allow ip from 10.0.0.1 to me  2049,111,1022 via fxp0 setup 
keep-state

If I disable the firewall it all goes smootly.

Could you please help me?

Ciao
Vittorio
