Download the edge router code from http://edge.fireplug.net. It has a
firewall script that includes optional tunnels using IPIP. Currently
it is using 2.1.132 but should work fine with 2.2.x.
Boils down to:
ip tunnel add $tIF mode $tTYPE remote $tVIA local $oIP
ip addr add $tIP dev $tIF
ip link set $tIF up
ip route add $tNET dev $tIF
Where
$tIF is the tunnel interface you wish to use
$tTYPE is IPIP or GRE
$tVIA is the remote IP address
$oIP is the local exterior IP address
$tIP is the local inside IP address for this end of the tunnel
$tNET is the remote network
