[OLSR-users] Problem concerning the use of HNA !!

[Andreas Tønnesen]

Hi,

This issue has been discussed many times before on the list ;-)

OLSR is not responsible for external routing. All olsrd can do is
create an aggregated route to the HNA announce network. The gateway
node must either implement NAT or the nodes in the foregin network must 
be able to route back into your OLSR network.
The easiest solution is to set up NAT on your gateway.
