Introduction:

IP Forwarding allows your internal network to communicate with the internet.

Aim:

Have IP Forwarding to start during boot-up.

Requirements:

None.

Procedure:

• Log in as root
• Open Terminal
• # cd /etc/init.d
• Copy the following script into this directory - I usually put it on a floppy. (Hint: right-click the link and choose 'Save link as...'):
• ip_forwarding
  
• # chmod 755 ip_forwarding
• # chkconfig --add ip_forwarding
• # service ip_forwarding restart

Testing:

• # cat /proc/sys/net/ipv4/ip_forward
• This should return; '1'.
