I'm getting this error all the time since I've set up my FreeBSD 4.4 with 
ipfw and natd as part of the kernel.

Dec  6 00:03:09 host4 natd[195]: failed to write packet back (Permission 
denied)
Dec  6 00:13:53 host4 last message repeated 26 times

This is the rules list I have for ipfw:

00050   24    1194 allow ip from any to any via lo0
00051    0       0 deny ip from any to 127.0.0.0/8
00052    0       0 deny ip from 127.0.0.0/8 to any
00060 1098  282242 divert 8668 ip from any to any via xl1
00100    0       0 allow ip from any to any via lo0
00100 4840 3315967 allow ip from any to any via xl0
00200    0       0 deny ip from any to 127.0.0.0/8

00400   39    2232 allow tcp from any to any out xmit xl1 setup
00401  933  257294 allow tcp from any to any via xl1 established
00450    0       0 allow tcp from any to any 22 setup
50000   50    9600 unreach host ip from any to any
65535    1     328 deny ip from any to any

Any suggestions as to what it could be? I'm really supmped - any help would 
be appreciated.
