Hi Peter,

something came to my mind as I read the mail from Ray: maybe its in your MASQ/SNAT rules on GW2. I guess you use Masquerading for outgoing trafic from NET2? In this case you should exclude traffic to 192.168.0.0/16 from this rule.

I dont use SuSEFirewall, but the shellcommand for SNAT is something like:

iptables -t nat -I POSTROUTING -s $ownnet -d ! 192.168.0.0/16 -j SNAT --to-source $badIP

where $ownnet is my internal (something like 192.168.22.0/24) and $badIP is the external IP of the FW.

Greetings, Thomas
