The incoming connections computer will assign IP addresses to the remote computers that connect to it. These addresses can be allocated in one of two ways:
If you want to specify a range of IP addresses, you must provide a starting IP address and an ending IP address for the range. Network Connections calculates the number of addresses that can be used within the starting and ending addresses of the range. For more information about specifying the range, and the effects of a subnet on the address range, see To configure an incoming connection to use TCP/IP.
If the incoming connections computer is attached to another network, and the specified address range consists of a subset of IP addresses for the network to which the computer is attached, you must ensure that the addresses in the range are not already assigned to other TCP/IP nodes within the attached network. This is recommended because using a subset of the larger network's addresses requires less manual configuration of the intranet nodes.
If you must use a range of addresses that is not a subset of the network to which the incoming connections computer is attached, then steps must be taken to ensure that computers on the network attached to the incoming connections computer can reach the incoming connection clients. To do this, on each of the computers on the network you can create a route to the incoming client computers with the IP address of the incoming connections computer as the associated gateway.
For more information, see To configure a default gateway.
