Re: [Bluez-users] A PAN newbie

[Eduardo Bezerra <edubezval@gmail.com>]

Hi all,

  Thanks for the quick response. It's truth that I get a second bnep
in the GN, the bnep1. But
I tried to continue the configuration with a "ifconfig bnep1 10.0.0.4"
and the problem kept.
I thinked that at this point (with the two PANU connected and
configured), I could ping
the bnep0 with the old PANU and ping the bnep1 with the new PANU, even
without the
bridge configuration in the GN.
  Ok, and how can I do a bridge configuration in the master ??
  Is it just creating statics routes between the two bnep's?


Thanks a lot,



Eduardo Bezerra Valentin
