Configuring the network tunnel service to manage TCP/IP connections from the network tunnel clients requires setting up IP address pools for the allocation of IP addresses to the clients. Setting up the address pools is typically done when you configure the network tunnel service. For information on how to initially set up IP address pools, see Configuring IP Address Pools.
When you create communities that will deploy the network tunnel clients to users, you must specify which of those IP address pools are available to members of that community. By default, AMC makes all configured address pools available; however, you can select specific IP address pools if necessary.
