3.5.2 IP Address and Subnet Mask-Continued
The subnet mask specifi es the network number portion of an IP address. Your WR3000
Wireless Router will compute the subnet mask automatically based on the IP address that you
entered. You don’t need to change the subnet mask computed by the WR3000 Wireless Router
unless you are instructed to do otherwise.
3.5.3 DNS Server Address Assignment
Use DNS (Domain Name System) to map a domain name to its corresponding IP address and
vice versa. For instance, the IP address of a web site with an URL of www.anycompany.com
could be 192.168.3.1. The DNS server is extremely important because without it, you must
know the IP address of a computer before you can access it.
There are two ways that an ISP disseminates the DNS server addresses.
1. The ISP tells you the DNS server addresses, usually in the form of an information sheet,
when you sign up. If your ISP gives you DNS server addresses, enter them in the DNS
Server fi elds in DHCP Setup.
2. Leave the DNS Server fi elds in DHCP Setup blank (for example 0.0.0.0). The WR3000
Access Point acts as a DNS proxy when this fi eld is blank.
3.5.4 WAN MAC Address
Every Ethernet device has a unique MAC (Media Access Control) address. The MAC address is
assigned at the factory and consists of six pairs of hexadecimal characters, for example, 00:A0:
C5:00:00:02.
You can confi gure the WAN port’s MAC address by either using the factory default or cloning the
MAC address from a workstation on your LAN. Once it is successfully confi gured, the address
will be copied to the “rom” fi le (ZyNOS confi guration fi le). It will not change unless you change
the setting or upload a different “rom” fi le.
ParkerVision recommends you clone the MAC address from a workstation on your LAN even if
your ISP does not require MAC address authentication.
Your WR3000 Wireless Router WAN port is always set at half-duplex mode as most cable/DSL
modems only support half-duplex mode. Make sure your modem is in half-duplex mode. Your
WR3000 Wireless Router supports full duplex mode on the LAN side.
Example of Network Properties for LAN Servers with Fixed IP Addresses:
Choose an IP address 192.168.1.2-192.168.150.32; 192.168.1.65-192.168.1.254.
Subnet mask 255.255.255.0
Gateway (or default route) 192.168.150.1 (WR3000 Wireless Router LAN IP)
