DHCP Server Settings

DHCP stands for Dynamic Host Control Protocol. The DIR-450 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-450. 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.
