Re: [B.A.T.M.A.N.] Fail to create tunnels using br-lan

Hi everyone, A student who is collaborating with me, Andrei, cc'ed, is carrying out traffic performance analysis in a mesh network (which uses batman-adv) in order to compare the benefits of introducing Simplemux [1]. Basically, simplemux multiplexes small packets in bigger packets and compresses them to reduce overhead. These packets are then sent through a tunnel to another end in the network. So far, simplemux shows very positive results by creating the tunnel in between two computers connected at each end of a multihop network composed by a chain of 5 nodes. The idea would be to test the performance benefits of simplemux when the tunnels are created between the mesh nodes instead, so they could aggregate, let's say, all the VoIP packets from different SIP clients calling other SIP clients in the mesh or via the gateway. The tunnels can be successfully created in OpenWRT, but it fails when assigning the physical interface the tunnel should use. It works when a physical interface is used, i.e. eth0, but fails with br-lan provided it is a virtual interface. # openvpn --mktun --dev tun0 --user root # ifconfig tun0 up # ./simplemux -i tun0 -e br-lan -M N -c 192.168.0.5 I was wondering if anyone in the list could point Andrei in the right direction. Thank you very much in advance.
