This is my last fragmentation question I swear :-) 

  When diverting udp  packets which are larger than MTU(1500) ipfw seems to 
divert the first and reject the second.
Here is tcpdump of the packets:


23:41:05.670408 192.168.1.3.1128 > 192.168.5.12.3322:  udp 1474 (frag 4127:1480@
0+)
23:41:05.670420 192.168.1.3 > 192.168.5.12: (frag 4127:2@1480)

Below is the log from ipfw.

Jan 26 23:40:56 richmond /kernel: ipfw: 60000 Divert 4422 UDP 192.168.1.3:1128 
192.168.5.12:3322 in via xl0
Jan 26 23:40:56 richmond /kernel: ipfw: -1 Refuse UDP 192.168.1.3 192.168.5.12 in via 
xl0 Fragment = 185



 Now i know that ipfw will drop tcp packets of length 1 is something like that 
what's going on here?

  Well if anyone can let me in on the meaning of the rejection message it
would be helpful.
