I'm running the newest version of SoftEther (Ver 4.28, Build 9669) on Windows 10 Pro.
The SoftEther specification states that AES is supported under L2TP/IPSec however, the server only advertises 3DES support. For example, in the SoftEther VPN Server Manager window, in the Encryption and Network menu, I have the encryption algorithm set to AES256-SHA256. Yet, when the server is queried with ike-scan, it only advertises support for 3DES:
Code: Select all
SA=(Enc=3DES Hash=SHA1 Auth=PSK Group=2:modp1024 LifeType=Seconds LifeDuration=28800)
Edit: AES with SHA-1 does not work either.
