Wireless Cable Voice Gateway Model CVG824G Reference Manual
Using the Gateway as a DHCP Server
By default, the gateway is a DHCP server. It can assign IP, DNS server, and default gateway addresses to all computers connected to the LAN. The default wireless voice gateway address is its LAN address. The wireless voice gateway assigns IP addresses to the network computers from a pool of addresses specified in the Starting Address and Ending Address fields. Each pool address is tested before it is assigned to avoid duplicate addresses on the LAN.
Note: If another device on your network is the DHCP server, or if you will manually 
configure the network settings of all of your computers, select No for the DHCP
Server. For more information about DHCP and IP addresses, see the link to “Preparing a Computer for Network Access:” in Appendix B.
The gateway 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 is the gateway’s LAN IP address.
•Primary DNS Server, if you entered a Primary DNS address in the Basic Settings page; otherwise, the gateway’s LAN IP address.
•Secondary DNS Server, if you entered a Secondary DNS address in the Basic Settings page.
Note: The gateway implements a DNS Relay function. When it receives a DNS request 
on the LAN, it passes it to the DNS server specified on the WAN. It then relays the
response back to the original requesting PC.
Configuring the LAN IP Settings
You can use the LAN IP Setup page to configure LAN IP services such as the IP address of the gateway and DHCP.
To configure the LAN IP:
1.Under Advance on the main menu, select LAN IP. The LAN IP screen will display.
2.Enter the
•LAN IP Address you want to assign to your gateway. The default is 192.168.0.1.
•Subnet Mask for your network IP address. The default is 255.255.255.0. (Unless you are implementing subnetting, use the default subnet mask.)
