I don't think you understood Bernds explanation. The idea is:
- Set up a static _host_ route to the ping destination trough the uplink 
interface.
- Now let dyn_gw dynamically add/remote the default route based on the 
pings.
- The pings will _always_ be routed through the host route so there is 
no need
for any hacks(like re-adding the default route or doing some sort of 
IP-routing bypass).

It should give you just what you want.


My other option(which Bernd also explained) is to have _dedicated_ 
gateways. That means
you have gateways that _only_ act as gateways. That means they do not 
themselves depend
on Internet connectivity. This is what the plugin was originally created 
for. The boxes
that ran this plugin were pure gateways dedicated to providing Internet 
access and if they
lost their link they should stop announcing themselves as a GW and just 
wait to recover.
The node it self never needs to have a "backup" Internet route trough 
the olsrd domain
since it's ONLY purpose is to serve Internet connectivity not to connect 
to Internet
themselves.
