Clients can’t connect via IPv6 to the server #382

Closed UnderEu closed 1 year ago

UnderEu commented 1 year ago

I’ve been using this for some time now and it’s been working great but I noticed that, besides my server machine being Dual-stacked (Public IPv6+IPv4), the clients can only connect to it via the legacy protocol (IPv4). I am not saying v6 doesn’t work on the VPN traffic itself (it does), my issue is that I can’t establish my connection via v6.

The address endpoint is reachable on both protocols and the firewall settings on my router + the server machine is set to allow incoming connections on both protocols as well.

Am I missing something?

Turns out my ISP box isn't clear about how it filters and blocks inbound connections and its Firewall, when enalbed, blocks every v6 incoming connection and there are no option to create rules or exceptions for specific hosts/ports.

Not a script issue
