I am using WireGuard on my iPhone, and the endpoint is specified by a domain name that has both AAAA and A record. When I turn on WireGuard in a network with dual IPv6 and IPv4, I find out that WireGuard chooses IPv4 by executing "wg" on my server. If I explicitly set the endpoint as IPv6 address, WireGuard works just fine, so it is not a misconfiguration on my server.
Most operating systems prioritize IPv6 over IPv4, so it is baffling why WireGuard iOS goes the other way. More importantly, this is not a theoretical discussion for me: in my case, IPv6 has better performance due to less congestion (as fewer people utilize it). I also have an IKEv2/IPSec VPN configured on the same server, and it performs better because it always prioritize IPv6. _______________________________________________ WireGuard mailing list WireGuard@lists.zx2c4.com https://lists.zx2c4.com/mailman/listinfo/wireguard
