The Internet connects millions of computer users throughout the
world. The vast majority of the computer users on the Internet
are friendly and have no intention of breaking into, stealing
from, or damaging your network. However, there are hackers
who may try to break into your network.
The options on this screen enable you to allow PING from the
internet and to disable the firewall as shown below:
Allow PING from the Internet — PING is a utility, which is
used to determine whether a device is active at the specified
IP address. PING is normally used to test the physical
connection between two devices, to ensure that everything is
working correctly.
By default the Router has PING disabled so that it does not
respond to PING requests. This makes the device more diffi-
cult to find on the Internet and less prone to attack.
This feature is enabled by clicking on the check box so that a
tick can be seen and then selecting Apply.
3Com recommends that you leave Allow PING from the Internet
disabled as this provides greater security.
Disable SPI Firewall — The firewall feature detects attack
patterns used by hackers on the Internet and once detected
will block their access to your network. The firewall feature is
disabled by clicking on the check box so that a tick can be
seen and then clicking Apply.
3Com recommends that you leave the firewall feature enabled
(checkbox cleared) for normal use. You may wish to turn it off
for diagnostic purposes.
