DI-304/DI-304M ISDN Remote Router
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/netmask is for
private users or NAT users, and the second IP address/netmask 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.
