There is only one public address, which is the one on bge0. It's the first time I've setup a OpenBSD machine and I'm happy to learn of a better way to accomplish this! Based on various docs I've read I understood that I needed to create such a bridge, and since it worked I assumed it was the way to this. But I just shut down the bridge and our network still works. Thanks! Best regards, Andreas
