Just write it down at yours command line and press enter.
After that see whether worked with less /proc/sys/net/ipv4/ip_forward.
If there is 1 that's it...

if you want it to be maintained through a reboot yo ould add it to /etc/rc.d/rc.local (this file gets run at start up).

Before you actually do this though it would be a good idea to set up your firewall first. Once you set ip_forward to 1 packets can be sent through your network and if you have no firewall you might get a nasty result.
