I think for now port 8080 is open too. Can anybody make obfs4 server with these ips and port 8080?

I stopped snowflake and now a bridge is running on my dynIP.

But I have that in the log :-(
Jul 30 16:48:29 t520 Tor-01[93466]: The IPv4 ORPort address 127.0.0.1 does not match the descriptor address 203.0.113.18. If you have a static public IPv4 address, use 'Address <IPv4>' and 'OutboundBindAddress <IPv4>'. If you are behind a NAT, use two ORPort lines: 'ORPort <PublicPort> NoListen' and 'ORPort <InternalPort> NoAdvertise'.
Jul 30 16:48:29 t520 Tor-01[93466]: The IPv6 ORPort address ::1 does not match the descriptor address 2001:db8:1234:1:bbbb:eeee:eeee:ffff. If you have a static public IPv4 address, use 'Address <IPv6>' and 'OutboundBindAddress <IPv6>'. If you are behind a NAT, use two ORPort lines: 'ORPort <PublicPort> NoListen' and 'ORPort <InternalPort> NoAdvertise'.

I don't know if I should ignore that or better configure it that way:
ORPort 127.0.0.1:8443 NoListen
ORPort 8443 NoAdvertise
ORPort [::1]:8443 NoListen
ORPort 8443 NoAdvertise

I'm aware of
https://gitlab.torproject.org/tpo/core/tor/-/issues/40208
I hope to get it done with scipting on my Mikrotik, or switch to ipv4 only.

frontdesk@xxxxxxxxxxxxxx has no PGP key, can I send you or meskio the bridgeline?

Bridgeline must be:
Bridge obfs4 <IP ADDRESS>:<PORT> <FINGERPRINT> cert=abra+kadabra iat-mode=0
But DynIP changes every few days. Do you also give the bridge users myrouter.example.net?

Because of your post in the forum:
https://forum.torproject.org/t/orport-127-0-0-1-auto/8470
should we do this with all running bridges, or only the hidden ones?

Other way around:
ORPort 8443?NoListen
ORPort 127.0.0.1:8443?NoAdvertise
