The OLSR parameters were borrowed from Freifunk Berlin (on the assumption they have successfully deployed such on a large scale). Also note that the repeater nodes have configuration for non-existent "wan" interfaces, and that the gateway node has no firewall restrictions on its (existent) wan interface, since this is just a test mesh.<br><br><div>This setup works reasonably so far, with the
specific exception of some repeater nodes (but not all!) with 2 hops
failing to build a functional SmartGateway tunnel back to the gateway
node, e.g. they get no route to the outside. The reason for this
exception is thus far unknown to me, despite some hair pulling.<br></div><br></div><b>Gateway node ...<br></b><br></div><i>/etc/config/wireless:</i><br>config wifi-device radio0<br> option type
