Filtering Internet access

You can use the Filter menu to make settings that will enhance the security of your

network. You can

◆ protect your LAN against ping attacks from the Internet (see below),

◆ restrict Internet access to selected PC's and for selected services (see below), and

◆ restrict access by members of your LAN to selected websites (see page 85).

Preventing ping attacks from the Internet

Ping is a command which can be used on the Internet to find out the existence of

network members. If your router is 'visible' on the Internet, it may be an easy target for

attack by hackers. You should therefore deselect this option.

For test purposes, trouble-shooting etc. it may be useful to reply to a ping, and you can

enable the option temporarily in this case.

◆ In the Filter menu, select Internet Services.

◆ Select or deselect WAN Port Ping Reply.

◆ Click on APPLY to apply the setting.

Restricting access of local PC's to the Internet

By default, your router is set up to allow all PC's that are logged on to it to use all Internet

services.

You can use the filter function to specify which PC's are allowed to use which service,

and so enhance the security of your LAN. To do this, use the Filter screen shown above.

You will find an example of how to create an Internet filter in "Practical

Tips and Configuration Examples" on the CD supplied.
