3.4.2 DHCP Settings
DHCP (Dynamic Host Configuration Protocol) allows the individual client (computers) to obtain the
TCP/IP configuration at start-up from the centralize DHCP server. You can configure this router as a DHCP
server or disable it. DHCP server can assign IP address, an IP default gateway and DNS server to DHCP
clients. This router can also act as a surrogate DHCP server (DHCP Proxy) where it relays IP address
assignment from an actual real DHCP server to clients.
If the DHCP was disabled, the screen of Fig 3.4.2-1 appears. You can enable/disable DHCP Server or
DHCP Proxy.
