The Security Settings (Firewall) menu provides an option for enabling or disabling your
Gateway’s firewall setting. To access the Security Settings (Firewall) menu, click
Firewall
in
the menu bar. Figure 39 shows an example of the menu.
By default, your Gateway’s firewall settings are enabled. To disable the firewall, uncheck
Enable Firewall Module
and click
Apply
. Disabling the firewall hides the submenus below
the
Firewall
menu.
The Security Settings (Firewall) menu also provides an option for enabling or disabling the
Session Initiation Protocol (SIP) application-layer gateway service on the Gateway firewall.
This option allows SIP signaling requests to traverse directly through the Gateway to the
destination device.
