DHCP Server: These settings allow you to configure the Modem Router‘s Dynamic Host  
Configuration Protocol (DHCP) server function. The DHCP server is enabled by default for the  
Modem Router’s Ethernet LAN interface. DHCP service will supply IP settings to computers  
which are configured to automatically obtain IP settings that are connected to the Modem  
Router though the Ethernet port. When the Modem Router is set for DHCP, it becomes the  
default gateway for DHCP client connected to it. Keep in mind that if you change the IP  
address of the Modem Router, you must change the range of IP addresses in the pool used  
for DHCP on the LAN.  
Start IP Address: Enter a value for the DHCP server to start with when issuing IP  
addresses. Because the default IP address for the Modem Router is 192.168.1.1, the  
default Start IP Address is 192.168.1.100, and the Start IP Address must be 192.168.1.100  
or greater, but smaller than 192.168.1.254.  
End IP Address: Enter a value for the DHCP server to end with when issuing IP  
addresses. The End IP Address must be smaller than 192.168.1.254. The default End IP  
Address is 192.168.1.254.  
Leased Time: The Leased Time is the amount of time in which a network user will be  
allowed connection to the Modem Router with their current dynamic IP address. Enter the  
amount of time, in hours, then the user will be “leased” this dynamic IP address. After the  
dynamic IP address has expired, the user will be automatically assigned a new dynamic IP  
address. The default is 1440 minutes.  
The detailed configuration about DHCP server, please refer to section 4.5 DHCP Server.

number defined in the Trigger Port field.  
2. The Modem Router records this connection, opens the incoming port or ports associated  
with this entry in the Port Triggering table, and associates them with the local host.  
3. When necessary, the external host will be able to connect to the local host using one of the  
ports defined in the Incoming Ports field.

Note:  
1. When the trigger connection is released, the corresponding opened ports will be closed.  
2. Each rule can only be used by one host on the LAN at a time. The trigger connection of other  
hosts on the LAN will be refused.  
3. Open Ports ranges cannot overlap each other.  
4.7.3 DMZ  
Choose menu “ForwardingDMZ”, and then you can view and configure DMZ host in the screen  
(shown in Figure 4-30).The DMZ host feature allows one local host to be exposed to the Internet  
for a special-purpose service such as Internet gaming or videoconferencing. The Modem Router  
forwards packets of all services to the DMZ host. Any PC whose port is being forwarded must  
have its DHCP client function disabled and should have a new static IP Address assigned to it  
because its IP Address may be changed when using the DHCP function.
