add a line to your firewall ( or on all the firewalls )
echo 1 > /proc/sys/net/ipv4/ip_forward which will allow traffic to a next
hop
and add a rules that states anything coming from the internal network ,
destination router Ethernet ip accept
What firewall application are you using ? ( IPCHAINS ? )

IP's 2-62 IP's 66-78 IP's 82-86 COR 1100
publicnet privatenet securenet wavenet
All clients use the eth1 of the firewall on there network for the
gateway and I have a question now:
How can I setup a transparent firewall that the clients can use the
network ethernet interface of the router as gateway ???
The same is for the ipac (Traffik-Counter)
Tesekkür Ederim
