I don't specifiy the ports for the venue server overall. Beside I think
bridging a whole venue server is not that well supported.
You have to specify the ports for each venue seperately. If you refer to
the ports of the VenueServer itself, these are configured through the
configuration. As fas I know through the VenueServer.cfg file, but I
didn't succeed in configuring it yet.
