You install Windows Server 2012 R2 on a standalone server named Server1. You configure Server1 as a VPN
server.
You need to ensure that client computers can establish PPTP connections to Server1.
Which two firewall rules should you create? (Each correct answer presents part of the solution. Choose two.)
A.
An inbound rule for protocol 47
B.
An outbound rule for protocol 47
C.
An inbound rule for TCP port 1723
D.
An inbound rule for TCP port 1701
E.
An outbound rule for TCP port 1723
F.
An outbound rule for TCP port 1701
Explanation:
The following is a list of firewall ports which need to be opened for the various VPN tunnel protocols:
For PPTP:
IP Protocol=TCP, TCP Port number=1723 <- Used by PPTP control path
IP Protocol=GRE (value 47) <- Used by PPTP data path
For L2TP:
IP Protocol Type=UDP, UDP Port Number=500 <- Used by IKEv1 (IPSec control path)
IP Protocol Type=UDP, UDP Port Number=4500 <- Used by IKEv1 (IPSec control path)
IP Protocol Type=ESP (value 50) <- Used by IPSec data path
For SSTP:
IP Protocol=TCP, TCP Port number=443 <- Used by SSTP control and data path
For IKEv2:
IP Protocol Type=UDP, UDP Port Number=500 <- Used by IKEv2 (IPSec control path)
IP Protocol Type=UDP, UDP Port Number=4500 <- Used by IKEv2 (IPSec control path)
IP Protocol Type=ESP (value 50) <- Used by IPSec data path
