DHCP Server Settings
DHCP stands for Dynamic Host Control Protocol. The DIR-857 has a built-in DHCP server. The DHCP Server will automatically assign an IP address 
to the computers on the LAN/private network. Be sure to set your computers to be DHCP clients by setting their TCP/IP settings to “Obtain an IP 
Address Automatically.” When you turn your computers on, they will automatically load the proper TCP/IP settings provided by the DIR-857. The 
DHCP Server will automatically allocate an unused IP address from the IP address pool to the requesting computer. You must specify the starting 
and ending address of the IP address pool.
Check this box to enable the DHCP server on your router. Uncheck to disable this function.
Enter the starting and ending IP addresses for the DHCP server’s IP assignment.
