The computer has two physical network interfaces and two ip addresses on each. Everything is working except that in the SDP header, there's always the first IP of eth0, 10.0.64.1. I'm creating two transports for TCP and an UDP with boundAddress and publicAddress set to 10.0.200.19. I'm creating the accounts explicitly binding them to the UDP transport. But the transport setting is still ignored. I'm clearly missing something important. Has anybody managed to configure the account/transport so that it really announces a specific address in the SDP header?
