4.8.5 Remote Management

You can configure the Remote Management function on this page shown in Figure 4-46. This

feature allows you to manage your Router from a remote location, via the Internet.

Figure 4-46

¾

Web Management Port

-

Web browser access normally uses the standard HTTP service

port 80. This router’s default remote management Web port number is 80. For greater

security, you can change the remote management Web interface to a custom port by

entering that number in this box provided. Choose a number between 1024 and 65534,

but do not use the number of any common service port.

¾

Remote Management IP Address -

This is the current address you will use when

accessing your router from the Internet. The default IP Address is 0.0.0.0. It means this

function is disabled. To enable this function, change the default IP Address to another IP

Address as desired.

To access the router, you will type your router's WAN IP Address into your browser's Address

(in IE) or Location (in Navigator) box, followed by a colon and the custom port number. For

example, if your Router's WAN address is 202.96.12.8 and you use port number 8080, enter

in your browser:

. You will be asked for the router's password. After

successfully entering the password, you will be able to access the router's Web-based utility.

)

Note:

Be sure to change the router's default password to a very secure password

.

4.8.6 Advanced Security

Using Advanced Security page (shown in Figure 4-47), you can protect the router from being

attacked by TCP-SYN Flood, UDP Flood and ICMP-Flood from LAN.
