Disable Firewall The Gateway contains a firewall that detects attack
patterns used by hackers on the Internet and once detected will block
their access to your network. When an attack is detected a log entry will
be generated and the Alert LED will be lit for 2 seconds. The firewall will
block Internet access to all unused TCP and UDP ports.

seen and then select
Apply .
3Com recommends that you leave the firewall enabled.

It is possible to administer the Gateway from four options:
1 Disable Remote Administration - This option is set as default.
2 Enable administration from a single Internet Host - Only the specified IP
address can manage the Gateway. Any other users will be rejected.
3 Enable administration from a whole subnet - This option allows a
number of users within a subnet to administer the Gateway.
4 Enable administration from any Internet Host - This options allows any
host to access the administration pages.
