Re: [B.A.T.M.A.N.] routing problem?

In my test, tcpdump showed that it uses the first (non-alias) address of the outgoing interface. No matter if the route to the destination specifies the src address or not. Did you use an alias interfaces for this scenrio? And even better, the traceroute on my notebook chooses the correct outgoing src address but unless i specify it also manually it does not work either. The reason is a corrupted udp checksum which is verified by the final destination of the packet. For correct routing between batman-nodes and non-batman nodes you need to set routes manually. If a multi-homed node is involved with the same netmask on multiple interfaces then you must also specify the src address for the manual routing entry like: ip r add 10.0.1.1/32 dev ath0 src 10.1.5.102 And on the batman-node you must either HNA announce the ip of the non-batman node using -a (this will automaticall disable the unreachable rule to hit for the ip address of the non-batman node). Or, just as you suggested, launch batman with the --no-unreachable-rule. ciao, axel
