3.4.1.3 DHCP
Dynamic Host Configuration Protocol (DHCP) allows the individual PC to obtain the TCP/IP
configuration from the centralized DHCP server. You can configure this router as a DHCP
server or disable it. The DHCP server can assign IP address, IP default gateway and DNS
server to DHCP clients. This router can also act as a DHCP server (DHCP Relay) where it
relays IP address assignment from an actual real DHCP server to clients. You can enable or
disable DHCP server.
Click
