Your network contains an ISA Server 2006 computer. A network rule defines a network address translation (NAT) relationship between the Internal network and the External network. The Internal network contains a Windows Server 2003 computer named Server1. You need to perform remote administration of Server1 from the External network by using Remote Desktop.
You also need to allow users to establish a Remote Desktop connection to Server1 by using the non-standard TCP port 12345. Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

A.
Configure a new protocol definition for TCP port 12345 inbound named RDP-x.

B.
Configure a new protocol definition for TCP port 12345 outbound named RDP-x.

C.
Create an access rule for Server1 that uses RDP-x.

D.
Create a server publishing rule for Server1 that uses RDP-x.
