[Olsr-users] What is the difference between dyn_gw and dyn_gw_plain

Mon Apr 7 16:08:21 CEST 2014

hello, thank you for your reports, so far I've tested both plugins but
concegui not make when he loses the route change to another route, even
just restarting the service to make it back to the correct route, I'll redo
the network, because it is small, to see if I can find where I am going

the more, thank you for your experiences.
