L2TP-IPSEC Win7 with AES256???

Hello,

with effort I set up my SoftEther VPN Server and enabled L2TP to support Windows clients without the must to install SoftEther VPN client.

From a Windows 7 machine I can connect via L2TP - it runs perfect :)

When I look into the Details of this connection on both sides I can see AEC-CBC (128) bit. But Windows since Vista also supports 192 and 256 bit AES.

I can not figure out where and how to enable it.

Must it be enabled in Softether or in Windows 7?

Thanks in advance

I have no idea but I can see AES-CBC(256 bits) when using my own server.

Hi kh_tsang

thank you for your quick reply. I found out I had to switch the security level to maximum in windows 7 client. After that I got also 256 bits.

In properties of the connection in windows there is a tab -> security and within that there is the dropdown where you can set the security level.

Thanks again ;)

Maybe Windows 10 connects using AES-CBC(256 bits) by default.
