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.
Network Protocols. Note that certain services such as IPSec and Microsoft's PPTP use non-TCP/UDP protocols so they may be more complicated to use. In particular, PPTP uses GRE (protocol 47) and IPSec uses ESP (protocol 50) and AH (protocol 51). Protocol numbers are not the same as port numbers.ote that certain services such as IPSec and Microsoft's PPTP use non-TCP/UDP protocols so they may be more complicated to use.
