You work as an IT engineer in an international company which is named WINTEL. You are in charge of the network of the company. You install Windows Small Business Server (SBS) 2008 on a sever which is named server1 and you enable a virtual private network (VPN) on the server. You have an external firewall device installed on your network. When the users plan to use the VPN to connect to the network, each of them gives a report that they get the error message as the following: Error 628:
This may because the port is disconnected.
This may because the remote computer terminates the connection before it could be completed.
This problem is most likely a modem or phone line noise issue or blocking port issue. Now you are assigned a task to make sure that all users can use the VPN to connect to the network, so what should you do?
A.
You should enable protocol 47 (GRE) on the external firewall device.
B.
You should enable protocol 45 (IDRP) on the external firewall device.
C.
You should enable protocol 46 (RSVP) on the external firewall device.
