One of the primary duties of a Gateway Enforcer appliance is to check that all computers that try to access the network are running the client. Some computers may not be running the Windows operating system or may not be running the client.

For example, VPN and wireless servers do not typically run the client. In addition, a network setup may include the devices that normally access the network and run an operating system other than Windows. If these computers need to bypass a Gateway Enforcer appliance, you need to make sure that the Gateway Enforcer appliance knows about them. You can accomplish this objective by creating a range of trusted external IP addresses. In addition, you must also assign an IP address from that IP address range to a client.

See Specifying trusted external IP addresses.
