[B.A.T.M.A.N.] problems detecting gw

Hi all,

I'm new in batman. Recently I have installed batman-0.3 and vis as well, but it seems not detecting the gw. Actually I have two questions:

1- What is the procedure to identify gw?

I have initiated the daemon in the node switched into a ethernet like -a 1.2.3.4/16 -g 7 -s 2.3.4.5 Then in other nodes I begin the daemon in second option and always "No gateways in range..." is displayed.

2- How to use the visualization server?

Is possible to use the same interface of batman protocol to receive visualization info? or it should be an alias or something like that? As I understood I have to download s3d to display the vis info, is that correct?

Sorry for my english and Thanks a lot!
