SSTP. Secure Socket Tunneling Protocol (SSTP) is a new tunneling protocol that uses the HTTPS protocol over TCP port 443 to pass traffic through firewalls and Web proxies that might block PPTP and L2TP/IPsec traffic.
IPSec does not work on an OSI layer. It is part of the TCP/IP model. When used as a tunneling layer, it is effectively layer 2.5. When just used as an annotation, itâs an IP option and thus part of the network layer. Views Â· View Upvotes.
