Cingular Communication Manager Help

Using the CheckPoint VPN client

Although CheckPoint's VPN client provides a command line interface that

applications such as Cingular Communication Manager can use to establish

connections, the user cannot access other modes of the CheckPoint VPN

client while the client is in command line mode.

What does this mean for CheckPoint VPN users? Essentially, you should

keep Cingular Communication Manager open only when you have an

active wireless connection open. If you want to establish another type of

connection (LAN , dialup, etc.) with the CheckPoint VPN client, you MUST

shut down the Communication Manager first. When Communication

Manager shuts down, it will put the VPN client back into a mode that users

can access.

Using the NetMotion VPN Client

NetMotion's VPN client takes complete control of all data communication

to and from a PC. This forces all data communication applications to go

through the “tunnel” it creates. However, Communication Manager needs

to bypass this tunnel in order to establish connections. Communication

Manager will accomplish this in one of the following ways:

• The NetMotion VPN client maintains a list of applications that are

allowed to bypass its VPN tunnel. If your VPN administrator has added

Communication Manager to this list, Communication Manager can

establish connections without interrupting the operation of the

NetMotion client.

• If Communication Manager has not been added to NetMotion's bypass

list, Communication Manager will detect that the NetMotion client is

interfering with its operations when it attempts to establish a

connection. When this happens, it will instruct the NetMotion client to

enter bypass mode (which allows all applications to bypass its tunnel)

while the connection is being established. Once the connection has been

successfully established, Communication Manager will return the

NetMotion client to its normal operating mode.
