[Olsr-users] Received HNA from NON SYM neighbor

Fri Nov 21 18:55:35 CET 2008

Hi Aaron,

One of my tests is very simple:  I have one x86 (WRAP) box connected to
the Internet with a single wireless card/antenna and I have a box board
with just the wireless card.

By putting in a static route on the 2nd box I have Internet access.

I'm using the same OLSRd configuration in both boxes EXCEPT that on the
2nd box I have the Hna4 section commented out.  I'm not using the dyn_gw
plugin.

If you'd like I can copy & paste HTTP info text and debug output?

The configuration file I'm using (2nd box with Hna4 commented out) is below

thanks,

Derek
