From the stats snowflake iseems to be working:
2022/02/18 19:29:59 In the last 1h0m0s, there are 13 connections.
Traffic Relayed ↑ 192 MB, ↓ 192 MB.
2022/02/18 20:29:59 In the last 1h0m0s, there are 21 connections.
Traffic Relayed ↑ 451 MB, ↓ 451 MB.
2022/02/18 21:29:59 In the last 1h0m0s, there are 9 connections. Traffic
Relayed ↑ 236 MB, ↓ 236 MB.
but b/c I do have a rather restrict inbound firewall rule set I'm
wondering about that.
I think it works without open ports by initiating the traffic from the inside on both ends. I used https://github.com/pion/stun/tree/master/cmd/stun-nat-behaviour to get a better understanding of the effects of my current setup.
Maybe that can help you too. Best regards
