Which two firewall rules should you create?

You install Windows Server 2012 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. Choosetwo.)

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:
To enable VPN tunnels between individual host computers or entire networks that have a firewall between
them, you must open the following ports:
PPTP
To allow PPTP tunnel maintenance traffic, open TCP 1723. To allow PPTP tunneled data to pass through
router, open Protocol ID 47. http://www.windowsitpro.com/article/pptp/which-ports-do-you-need-to-open-on-afirewall-to-
allow-pptp-andl2tp-over-ipsec-vpn-tunnels–46811
If you use a personal firewall or a broadband router, or if there are routers or firewalls between theVPN client
and the VPN server, the following ports and protocol must be enabled for PPTP on all firewalls and routers that
are between the VPN client and the VPN server:
Client ports Server port Protocol
1024-65535/TCP 1723/TCP PPTP
Additionally, you must enable IP PROTOCOL 47 (GRE).
