Incoming connections and IP addresses
The incoming connections computer assigns IP addresses to the remote computers that connect to it. The IP address is assigned in one of two ways:
| • | They are automatically allocated by DHCP. |
| • | They are assigned based on a range of addresses that is defined in the TCP/IP properties for the incoming connection. |
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 affects 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 computer 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.
| • | If the incoming connections computer has Internet Connection Sharing (ICS) enabled on a dial-up, VPN, or local area connection, then no special configuration is required. The DHCP addressing in ICS configures the client computers on the network to use the ICS host computer as the default gateway. |
For more information, see To configure a default gateway
Note
| • | Internet Connection Sharing cannot be enabled on incoming connections. |
