[OLSR-users] Anyone tried two nodes with internet connection?

[Rajesh Narayanan]

Hi,

Looks like we might be on to a bug here in the olsr dyn-gw. Yes, my opinion
is the same as yours. The default route should be removed if the pings do
not go through that route. Then I am sure it will behave correctly.

For clarification to everyone regarding my setup.
Node1 and 2 : Linksys WRT54G routers running the OpenWrt , WhiteRussian,
Release RC4
OLSR: compiled for RC4.

For sake of simplicity please ignore the LaptopsA and B. My apologies its
just confusing it. The laptops are being used mainly for accessing the
Linksys routers console via SSH.

Thanks,
Rajesh.
