• WA N These fields display the IP Address, Subnet Mask and Gateway IP
of the Router as seen by external users on the Internet.
• DNS (Domain Name Server) IP Address This field shows the IP
Address of the DNS currently being used. Multiple DNS IP settings are
common. The first available DNS entry is used in most cases.
DHCP
A DHCP (Dynamic Host Configuration Protocol) Server automatically
assigns IP addresses to each computer on your network. Unless you already
have one, it is highly recommended that the Router be set up as a DHCP
server.
• DHCP Server Check the Enable option to enable the DHCP server
option of the Router. If you already have a DHCP server on your network,
set the Router's DHCP option to Disable.
• Starting IP Address Enter a numerical value for the DHCP server to
start with when issuing IP addresses.
• Number of DHCP users Enter the maximum number of PCs that you
want the DHCP server to assign IP addresses to, with the absolute maxi-
mum being 253.
• DHCP Client Table Click on the Client Table button to show the current
DHCP Client information. (This information is stored in temporary mem-
ory, so the list of clients could disappear.)
