Guidelines For Enhancing Security With Your Firewall
1 Change the default password via Web Configurator.
2 Think about access control before you connect to the network in any way, including attaching a
modem to the port.
3 Limit who can access your router.
4 Don't enable any local service (such as NTP) that you don't use. Any enabled service could present
a potential security risk. A determined hacker might be able to find creative ways to misuse the
enabled services to access the firewall or the network.
5 For local services that are enabled, protect against misuse. Protect by configuring the services to
communicate only with specific peers, and protect by configuring rules to block packets for the
services at specific interfaces.
6 Protect against IP spoofing by making sure the firewall is active.
7 Keep the firewall in a secured (locked) room.
