LAN IP Addresses Range Enter your IP addresses range, which IP addresses are provided by
ISP. If you have multiple IP ranges, you need setup group1 and
group 2.
You can also setup the default gateway and IP range in the group 2.
DMZ Setting
For some network environments, an independent DMZ port may be required to set up externally
connected servers such as WEB and Mail servers. Therefore, the device supports a set of independent DMZ
ports for users to set up connections for servers with real IP addresses. The DMZ ports act as bridges
between the Internet and LANs.
IP address: Indicates the current default static IP address.
Config.: Indicates an advanced configuration modification: Click Edit to enter the advanced configuration
page.
The DMZ configuration can be classified by Subnet and Range:
Subnet
：
The DMZ and WAN located in different Subnets
For example: If the ISP issued 16 real IP addresses: 220.243.230.1-16 with Mask 255.255.255.240,
users have to separate the 16 IP addresses into two groups: 220.243.230.1-8 with Mask 255.255.255.248,
and 220.243.230.9-16 with Mask 255.255.255.248 and then set the device and the gateway in the same
group with the other group in the DMZ.
