Configuring Your Gateway
Configuring Access Control The Access Control menu lets you enable access control to block traffic at the Gateway's
LAN interfaces from accessing the Internet.
To access the Access Control menu, click Firewall in the menu bar and then click the
Access Control submenu in the menu bar.
By default, your Gateway does not block attempts to access the LAN from the Internet. To
enable access control, check Enable Access Control.

Configuring Special Applications Using the Special Application menu, you can configure your Gateway to detect port triggers
for detect multiple-session applications and allow them to pass the firewall. For special
applications, besides the initial communication session, there are multiple related sessions
created during the protocol communications. Normally, a normal treats the triggered
sessions as independent sessions and blocks them. However, your Gateway can co-relate
the triggered sessions with the initial session and group them together in the NAT session
table. As a result, you need only specify which protocol type and port number you want to
track, as well as some other related parameters. In this way, the Gateway can pass the
special applications according to the supplied information.
