I have a copy of suse linux enterprise server 10 installed. And my PC is a router of my home. I want to enable the IP-forward to make my subnet can access the internet. I found there's a string "#net.ipv6.conf.all.forwarding = 1" in the file "/etc/sysctl.conf". And I've tried to add a new line with its style "net.ipv4.conf.all.forwarding = 1".(Someone told me that add this line "net.ipv4.ip_forward = 1" will make it working. But it seems unfunctional.) And then restart the PC, type "cat /proc/sys/net/ipv4/ip_forward" it returns 0, it means all the way I've tried above can't set ip-forward enabled. I know there's a checkbox in the route of yast2. But it does NOT work at all! You can set it, reboot, and type "cat /proc/sys/net/ipv4/ip_forward" to verify. Any one knows how to make it workingThanks
