The router has IPv6. room.sudoroom.org has both an A record and AAAA record. If the router forwards the port to another machine for IPv4 only, clients may connect unsuccessfully to the IPv6 address first before connecting to the IPv4 address. This adds a significant delay during connection since Mumble seems to not connect to both addresses simultaneously but waits for one to time out before connecting to the other.
