Was alone yesterday in Zwift, didn’t do too much because I was doing a workout. Today I was going to ride ZSUN social ride. It was empty again. Had to fire up tcpdump to see that Zwift had a requirement for a new tcp port: 3023. Why can’t Zwift document this? Not everyone has a firewall that is open. So I missed the social ride.
So I have tcp 80, 443, 3023, 21587 and udp 3022 open for Zwift. I’m not sure that is all ports required, I did see others today. I ask that Zwift document required ports and notify when adding new ports.
