Settings – DHCP Server
The GWR-HS Router can be used as a DHCP (Dynamic Host Configuration Protocol) server on your network.
A DHCP server automatically assigns available IP addresses to computers on your network. If you choose to enable
the DHCP server option, all of the computers on your LAN must be set to obtain an IP address automatically from a
DHCP server. (By default, Windows computers are set to obtain an IP automatically.)
To use the GWR-HS Router as your network’s DHCP server, click
DHCP Server
Tab for DHCP Server setup.
The GWR-HS Router has built–in DHCP server capability that assigns IP addresses and DNS servers to systems that
support DHCP client capability.
