4.6.1  DHCP Settings 
The router is set up by default as a DHCP (Dynamic Host Configuration Protocol) server, which 
provides the TCP/IP configurati on for all the PC(s) that are connec ted to the router on the LAN. 
The DHCP Server can be conf igured on the page (shown in Figure 4-22): 
 
Figure 4-22 DHCP Settings 
¾ DHCP Server - Enable  or Disable the DHCP server. If you disable the Server, you must 
have another DHCP server within your network  or else you must manually configure the 
computer. 
¾  Start IP Address -  This field specifies the first of  the addresses in the IP address pool. 
192.168.1.100 is the def ault start address. 
¾ End IP Address -  This field specifies the last of the addresses in the IP address pool.  
						

							TL-WR542G54Mbps Wireless Router User Guide 
 38192.168.1.199 is the 
default end address. 
¾ Address Lease Time -  The Address Lease Time  is the amount of time in which a network 
user will be allowed connection to  the router with their current dynamic IP Address. Enter the 
amount of time, in minutes. The user will be leas ed this dynamic IP Address. The range of 
the time is 1 ~ 2880 minutes. The default value is 120 minutes. 
¾  Default Gateway -  (Optional.) Suggest to input the IP address of the LAN port of the router, 
default value is 192.168.1.1 
¾  Default Domain -  (Optional.) Input the domai n name of your network. 
¾ Primary DNS -  (Optional.) Input the DNS IP address prov ided by your ISP. Or consult your 
ISP.

4.6.3 Address Reservation 
When you specify a reserved IP  address for a PC on the LAN, that PC will always receive the 
same IP address each time when it accesses  the DHCP server. Reserved IP addresses should 
be assigned to servers that require permanent  IP settings. This page is used for address 
reservation (shown in 
Figure 4-24). 
 
Figure 4-24 Address Reservation 
¾  MAC Address -  The MAC address of the PC of whic h you want to reserve IP address. 
¾ Assigned IP Address -  The IP address of the router reserved. 
¾ Status  -  The status of this entry either  Enabled or Disabled. 
 
To Reserve IP addresses:   
1. Click the  Add New button . (Pop-up Figure 4-25)

Virtual servers can be used for setting up public se rvices on your LAN, such as DNS, Email and 
FTP. A virtual server is defined as  a service port, and all requests from  the Internet to this service 
port will be redirected to the com puter specified by the server IP. Any PC that was used for a 
virtual server must have a static or reserved  IP Address because its IP Address may change 
when using the DHCP function.  You can set up virtual servers on this page, shown in Figure 
4-27:
