CentOS5.3 / GRE Tunnel setup
 

I am working through Jeremy Garcia's article on setting Squid up to use WCCP redirection. I have been able to do everything except get the GRE tunnel to configure correctly. I am sure I am missing a step somewhere, but haven't been able to track it down.

When I issue the command:

iptunnel add gre1 mode gre remote x.x.x.x local x.x.x.x dev eth0

it comes back and tells me ioctl: No such device.

My problem is, I did get it to work once, but after rebooting the box, keep getting that message.

Using CentOS 5.3 with the latest updates and Squid 2.6 stable21.

Any assistance would be greatly appreciated!

you have to add follow line in rc.local for load gre module at startup.

moprobe ip_gre
