A little trick for this is to listen on udp/53 which is almost always unblocked, even before captive portals

- unethical_ban 3y agoActually, I found ATT blocking inbound port 53 to my home. Maybe udp 443 could work?
- KaiserPro 3y agoyeah high rates of data over port 53 tends to trigger a lot of firewalls. I've never had much success with it. 443 is much more likley to be let past, with the popularity of QUIC.
- threeio 3y agoI once used port 53 for all my communications at a hotel that was charing metering bandwidth by the gb... it was a magical weekend of DNS passthrough with video calls, etc. 53 is my go to port when the network is wonky.
- codethief 3y agoCould you elaborate on your setup? Do you have a proxy / VPN server running on port 53 somewhere?
