I enabled a PPTP VPN on my SLES 11.1, and I want to add a iptables policy like below:
iptables -I FORWARD -s -j ACCEPT
I don't know how to add this kind of forward policy in yast2/yast firewall tool,
so I just add it in rc.local. now I found every few seconds later, this policy will gone,
I don't know what application remove it, so my solution is use screen to run this command
"watch -n 5 iptables -I FORWARD -s -j ACCEPT".
seems this is a stupid solution, does any one know how to solve this issue? please help me.
