I figured I could do that but the amount of traffic going through from this

and allows you to sort & filter it?
I have a small LAN at home connected up to the net via a DSL modem on a gateway
machine running lenny and iptables.
I have a problem with some software running on a windows machine on the LAN
where the company who wrote the sofware say that there must be something wrong
with my internet connection, but can't help any further.
You can set a log-target in your firewall for these windows mashine, so
you can see what connection the mashine want to do.
I think on
iptables -A FORWARD -s <windows-IP> -o <DSL-device> \
-m state --state NEW -j LOG --log-prefix 'WIN-LOG: '
This rule logs only the first paket from new conections.
So i think its log not to many.
But you can test wiresharke for sniffing.
OK I'll take a look at wiresharke. Thanks
