Is anyone using AFS (either client or server) on a solaris 10 system with 
ipfilter running that can share their rule sets?

I am seeing large numbers of blocked fragmented packets, which is killing 
the performance.

My ruleset looks something like this:

pass out all keep state keep frags
block in log all
pass in log quick proto udp from any port 6999 >< 7010 to any port =
 	afs3-callback keep state keep frags
pass in log quick proto udp from any to any port = afs3-fileserver keep
 	state keep frags
pass in log quick proto udp from any to any port = afs3-volser keep state
 	keep frags
pass in log quick proto udp from any to any port = afs3-errors keep state
 	keep frags
pass in log quick proto udp from any to any port = afs3-bos keep state
 	keep frags
pass in log quick proto udp from any to any port = afs3-update keep state
 	keep frags
pass in log quick proto udp from any to any port = afs3-rmtsys keep state
 	keep frags


And ipmon is showing blocked packets like this:
