I've setup a site-to-site SSTP... it works fine.

I have certs on both sides, and in SSTP, I have checked "VERIFY CLIENT CERTIFICATE" and "VERIFY SERVER CERTIFICATE"

It connects and works fine, however the ENCODING field in the interface on both sides is blank.

Is that field simply not used for SSTP, or is in not encrypted?

How can I be sure that the link is secure and encrypted?

I'm interested too
