[Olsr-users] OLSR Gateway & HNA Question

Thanks. I totally forgot about modifying the subnet mask field. Thank you.

1. Just to clarify the obvious:


The node is going to retransmit any traffic if the destination IP is within  ( to ) on the same NIC, right?

Please confirm.

2. I tried using Dynamic gateway: (dyn_gw version: olsrd_dyn_gw.so.0.4) However this plugin seems to have problem. 

When I start olsrd with this plugin, it returns the error - 
"HNA"/"" ... netmask_to_prefix: Got bogus netmask
Segmentation fault.

( My network of static IPs is of 10.1.18. series. I did not make any setting outside olsr.conf about this)

Please help.

You can announce any kind of address in an HNA. Of course the IP of the router 
itself must be a "olsr net ip".

You can use a HNA like this:


This will announce the addresses to
