routing problem

following Problem.
I configured my SuSE Linux 8.0 as a router. I4l, named, ip_forward, iptables (NAT/MASQUERADING) are running or are aktivatet.
I just can get a internet connection about the proxy server squid, but if i want to use other protocols i need functional routing.

(I had this configuration with routing some times before on run, but after reinstalling the system, it dont want to run correctly)

I believe that at my last configuration at the sysstart SETTING UP ROUTING starts. Now it don't start and i cant find a option to aktivate it.

If sombody have a idea, then write.

THX

I solve this problem by using SuSefirewall2.
