I am using Unik-OLSR with Openwrt. I have multiple nodes with sometime
some hops. I have no problems at all except wireless propagation.

You could have a look at our firmware now named MBK. It's based on Openwrt
with a integrated micro web server. It's nearly complet with an easy 
user interface.
Just need to fill some values and push apply and reboot.

You'll find it at : http://wrt54g.free.fr/

I've stoped working on it for now because of my private life ... But I'm 
still here.

For your problem, you should
- make some testing point to point,
- desactivate firewall rules if no thing seems to work,
- work with IP not dns host names,
- make AP do IP forwarding,

and it should work.
