I like to use SSTP for a VPN over TCP, as it uses only one TCP port and it's very easy to setup. Now I have running one VPN of this kind, but I don't know how to change the ENCRYPTION algorithm. I like to use RC4 (aka Arcfour128) as it's less CPU consuming than AES256 (the default). In the documentation is described that Windows clients using SSTP connect to the Mikrotik server using RC4. So, I can assume that RC4 is supported. Then, how to force RC4 between two Mikrotik routers?
I wait for your comments.
