My ip address on the GRE is the same as the host address.

I create it like this:

/sbin/iptunnel add wccp0 mode gre remote $CISCO_IP local $HOST_IP dev eth0
/sbin/ifconfig wccp0 $HOST_IP netmask 255.255.255.255 up

It works perfectly. However, they say that you should know it will work because it is right, not assume it is right because it works!

Anyway, I hope it's right.
