Reference Manual for the RangeMax 240 Wireless Router WPNT834
Advanced Configuration of the Router 8-15
v1.0, November 2005
Using the Router as a DHCP server
By default, the router functions as a DHCP (Dynamic Host Configuration Protocol) server,
allowing it to assign IP, DNS server, and default gateway addresses to all computers connected to
the router's LAN. The assigned default gateway address is the LAN address of the router. The
router assigns IP addresses to the attached computers from a pool of addresses specified in this
menu. Each pool address is tested before it is assigned to avoid duplicate addresses on the LAN.
For most applications, the default DHCP and TCP/IP settings of the router are satisfactory. See
“Wireless Communications” in Appendix B for an explanation of DHCP and information about
how to assign IP addresses for your network.
Specify the pool of IP addresses to be assigned by setting the Starting IP Address and Ending IP
Address. These addresses should be part of the same IP address subnet as the router’s LAN IP
address. Using the default addressing scheme, you should define a range between 192.168.1.2 and
192.168.1.254, although you may wish to save part of the range for devices with fixed addresses.
The router delivers the following parameters to any LAN device that requests DHCP:
• An IP Address from the range you have defined
• Subnet Mask
• Gateway IP Address (the router’s LAN IP address)
• Primary DNS Server (if you entered a Primary DNS address in the Basic Settings menu;
otherwise, the router’s LAN IP address)
• Secondary DNS Server (if you entered a Secondary DNS address in the Basic Settings menu)
To select another device on your network as the DHCP server, or to manually configure the
network settings of all of your computers, clear the Use Router as DHCP Server check box.
Otherwise, leave it checked.
Using Address Reservation
When you specify a reserved IP address for a computer on the LAN, that computer will always
receive the same IP address each time it accesses the router’s DHCP server. Reserved IP addresses
should be assigned to computers or servers that require permanent IP settings.
To reserve an IP address:
1. Click the Add button.
2. In the IP Address box, type the IP address to assign to the computer or server.
(choose an IP address from the router’s LAN subnet, such as 192.168.1.x)
