Enabling Firewall and/or Intrusion Detection
* Intrusion Detection is for future feature.
You must create a security interface before you can enable Firewall and/or Intrusion Detection.
Security interfaces are based on existing LAN services. You must create a LAN service for every
security interface that you want to configure (From the “Security Interfaces” section, click on
“Add Interface”). If you see any error in the content of the security interfaces table, you must
delete the interface first and re-add the interface again. When you add the security interface, the
Type setting (internal/external) must follow the default rule (if it is a LAN side interface, the
Interface Type should be internal; if it is a WAN side interface, the Interface Type should be
external).
After the Firewall is enabled, you can set the Security Level. In the Security Level section, click
the “Security Level” drop-down list. Then click on the level that you want to set. Finally, click on
the Change Level button.
NAT Configuration
NAT stands for Network Address Translation, which is an Internet standard that enables a
local-area network to use one set of IP addresses for internal traffic and a second set of addresses
for external traffic. NAT, located where the LAN meets the Internet, makes all necessary IP
address translations.
1. In the “Security Interfaces” section of the page, you can see the newly created interfaces (see
Figure 6-40). To enable NAT, click the Enable NAT to internal interfaces button. Then the
page will refresh and the button will now read Disable NAT to internal interfaces.
