Hey, i dont know how mail lists work, as i dont get mails from the whole discussion. I make new Thread with all Details included.
I am running Windows 10 Enterprise, Windows 10 Home. My Router is Vodafone Station (Default Router). They might have remote access to fix problems, like all isps do.
When i do 1280 MTU, its fine. But its 100mbps maixmum with huge latency drops when i open some websites.
My Configurations:
[Interface]
PrivateKey = HIDDEN
Address = 10.0.0.2/32, 2a01::2/128
DNS = 20.199.177.73
MTU = 1280
[Peer]
PublicKey = oyq9egDqiRTgxKbvWonrkFavvp9JcIw40EJoWmjRD3Y=
AllowedIPs = 0.0.0.0/0, ::/0
Endpoint = 104.248.247.50:51820
PersistentKeepalive = 21
I did not change anything on Interface.
Ubuntu Server:
