hi all
i have freebsd 4.8 installed and i use ipfw2 with the rules

#!/bin/sh
fwcmd=/sbin/ipfw
${fwcmd} -f flush

#!/bin/sh
ipfw='/sbin/ipfw'
$ipfw -f flush

$ipfw add divert natd all from any to any via ppp0
$ipfw add allow log all from any to any

my local ethernet card has 192.168.133.7 ip address
and my ppp0 interface has 217.15.x.x ip address.

when i tried to connect to 195.54.192.44:21 from my local box i got the lines

Accept TCP 172.16.202.106:4802 195.54.192.44:21 out via ppp0
Accept TCP 195.54.192.44:21 172.16.202.106:4802 in via ppp0
and so on.

as i know 172.16.0.0 are gray addresses and i haven't got any 172.16.x.x networks
in my environment.
Could anybody tell me what 172.16.202.106:4802 does in my log file.

Thanks
vanyushenkov al
