hi all,

I have a problem with my Suse 8.1 routing.

I have a server with two network cards, one connected to LAN ( and the other is connected to ISP ( , Gateway

I've done : ... echo "1" > /proc/sys/net/ipv4/ip_forward

at this time I can route to internet from server , but when I set my client gateway's IP to they could not connec to internet , they cannot ping also.

iptable --list tell that every thing is accepted , (I have no firewall yet)

any guid??
thanks, mohammad

Just because iptables is accepting everything, it doesn't mean that it's
forwarding packets between the networks. You'd be best off installing a
firewalling script such as Shorewall, or at least using SuSE's built-in
firewalling via YaST. You'll have to use IP Masquerading in order to
use the internet with your internal machines. HTH.
