To use a fixed port, uncomment the [ServerTransportListenAddr](https://www.torproject.org/docs/tor-manual.html.en#ServerTransportListenAddr) option in your torrc. You can use [our reachability test](https://bridges.torproject.org/scan/) to see if your obfs4 port is reachable from the Internet. +--- +subtitle: How to deploy obfs4proxy Bridge on OpenBSD +--- +section: Bridge +--- +section_id: bridge
