Thanks for letting me use your server for testing, but unfortunately it is not useful for NAT-T connection. Unfortunately the NAT-T connection speed problem is not easy to find and fix. At the moment I do not know how long it will take, so I will promote the beta version to production and then take ...

Unfortunately the server I'm using for testing doesn't seem to work like yours.
Please, can you create a test account on your VPN server and send me a address, port, user and password privately so I can do some testing?

I did some tests with the SoftEther client and it doesn't seem possible to use UDP acceleration when the connection goes through VPN Azure. The connection status shows: Physical Underlay Protocol = TCP/IP via VPN Azure (IPv4) Protocol Details = IPv4 VPN Azure UDP Acceleration is Supported = No UDP A...

The problems will be solved in the next release...

As a starting point you might try setting the MTU to 1420 on both the client and server...
