ipfw FWD and NOT ME bug while SSHing ?

[hugle]

Hello all.
I've just noticed some problems here.... look :
whilee sshing to the server after running such command:

bash-2.05b# ipfw add 3032 fwd x.x.x.1 ip from 192.168.0.0/16 to not me && sleep 15 && ipfw delete 3032 &
 I've got 'disconencted' from ssh for 15 seconds, console hanged up.
But I was able to ping the machine
BUT I wasn't able to ssh to this machine with its IP 192.168.x.x while
sshing to x.x.x.59 to the same machine I've got IN (and after rule
automaticaly removed after 15 sec this ocnsole hanged up)

And after 15 seconds i was able to INPUT further..
Doesn anyone met this problem before?

PS.
03020      5274      4396532 fwd z.z.z.161 ip from 192.168.0.0/16 to not me dst-port 22
command like that didn't take any affect after adding, was able to
SSH.
