Basic Configuration and Internet Access  

Basic Setup (Setup First) 

This group includes Administrator Password Setup, Ethernet TCP/IP and DHCP 

Setup,and ISDN Setup. 

Changing the Administrator Password 

On first setup the router requires no password. However, for security reasons, we strongly 

recommend that you set an administrator password for the router. If you do not set a 

password for the router, any user can access the setting of the router and make changes 

randomly from local network or the Internet. 

Click Administrator Password Setup, the following screen will open. 

♦

Old Password – If this is the first time you enter this menu, leave this field 

blank. 

♦

New Password – Enter an administrator password. 

♦

Retype New Password – Type the password again to confirm. 

Configuring Ethernet TCP/IP Address and DHCP Server 

The Router has four Ethernet ports for connecting to the local Ethernet network and 

external broadband device (i.e. DSL modem/router or Cable modem). There are two sets 

of IP address settings for the Ethernet. The first IP address/net mask is for private users or 

NAT users, and the second IP address/subnet mask is for public users or pure router (not 

NAT) user. To allow access of public users you need to subscribe a globally reachable 

subnet from your ISP.
