[tor-relays] orport

[Astroskis Lists]

I'm not sure how TOR gets its addresses but sometimes you need to 
specify it directly, especially for bridges for some reason. Just use 
your whole IP

ORPort 123.456.789.123:80


Dont forget if you are mapping Obfs4 you need to add the permissions so 
obfs can go to a port that low


    /Don't forget to change the |ORPort|, |ServerTransportListenAddr|,
    |ContactInfo|, and |Nickname| options./

    //

      *

        /If you decide to use a fixed obfs4 port smaller than 1024 (for
        example 80 or 443), you will need to give obfs4
        |CAP_NET_BIND_SERVICE| capabilities to bind the port with a
        non-root user:/

        /|sudo setcap cap_net_bind_service=+ep /usr/bin/obfs4proxy|/

        /To work around systemd hardening, you will also need to set
        |NoNewPrivileges=no| in
        |/lib/systemd/system/tor at default.service| and
        |/lib/systemd/system/tor at .service| and then run |systemctl
        daemon-reload|. For more details, see ticket 18356
        <https://gitlab.torproject.org/tpo/core/tor/-/issues/18356>./

      *

        /Note that both Tor's OR port and its obfs4 port must be
        reachable. If your bridge is behind a firewall or NAT, make sure
        to open both ports. You can use our reachability test
        <https://bridges.torproject.org/scan/> to see if your obfs4 port
        is reachable from the Internet./
