Hello,

I tried setup NAT with IPFW, compiled my kernel and I found that there 
is very slow connection.
After I disabled NAT and IPFW then speed was increased.

64-bit FreeBSD 9-CURRENT :
With IPFW: 1.2 MB/sec
Without IPFW: 33 MB/sec


my ipfw work with i386 (stable) without speed decreasing:

fw.test.conf:
-f flush
add 00050 divert 8668 ip4 from any to any via re0
add 00100 allow ip from any to any via lo0
add 00200 deny ip from any to 127.0.0.0/8
add 00300 deny ip from 127.0.0.0/8 to any
