For L2TP:
IP Protocol Type=UDP, UDP Port Number=500
IP Protocol Type=UDP, UDP Port Number=4500
IP Protocol Type=ESP (value 50)
For SSTP:
IP Prot
ocol=TCP, TCP Port number=443
For IKEv2:
IP Protocol Type=UDP, UDP Port Number=500
IP Protocol Type=UDP, UDP Port Number=4500
IP Protocol Type
=ESP (value 50)
