[84ian]

I've set my rules and chains..watever u call them.
However when i tried activating the commands:
>/proc/sys/net/ipv4/ip_forward
* Permission denied*
i've tried changing the mode with chmod u+x but nothing happens....help?? Thanxs alot~

If you as, your logged in, own the file and the permissions are set correctly and you still get the permission denied error, try logging in and running it as root.

i am logged in as root...tried changing the /etc/sysct1.conf by changing the value to 1 ...but still nothinghappens..even rebooted the comp..
??how??

Blind leading the blind here...? :D


From the looks of it you're trying to run the file. What you really need to do is type:


echo "1" > /proc/sys/net/ipv4/ip_forward


as root, and all should be fine. I think.


I'm not sure if you need the iptables' nat rule in there somewhere, but... meh... I don't know. :)

Yup. I've tried changing the boolean value ...
i typed cat ip_forward, it shows 1
however, the cmd still doesnt initialise.
what is the problem?

there is no cmd command, the /proc is a virtual file system with your computer's settings, there are no commands in it. now you have to make the firewall script in order to take advantage of ip forwarding.
