5-6 Managing 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 gateway’s LAN IP
address. Using the default addressing scheme, you should define a range between 192.168.0.10
and 192.168.0.253. The range of IP addresses between 192.168.0.2 and 192.168.0.9 can be used
for devices with fixed addresses.
The gateway will deliver 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 menu;
otherwise, the gateway’s LAN IP address
• Secondary DNS Server, if you entered a Secondary DNS address in the Basic Settings menu.
DHCP Client Lease Info
The DHCP Client Lease Info table lists information about each PC that has been assigned a DHCP
lease by the gateway. The MAC address of the PC, IP address assigned and the expiration time of
the DHCP lease are listed.
You can manually revoke the DHCP leases by clicking Clear DHCP Leases.
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.
