7 SVG2500 FIREWALL PAGES
The SVG2500 Firewall Pages allow you to configure the SVG2500
firewall filters and firewall alert notifications.
You can click any Firewall submenu option to view or change the
firewall configuration information for that option.
For information about how the firewall can affect gaming, see
Gaming Configuration Guidelines .
The predefined policies provide outbound Internet access for computers on the
SVG2500 LAN. The SVG2500 firewall uses
stateful
-inspection
to allow inbound
responses when there already is an outbound session running that corresponds to
the data flow. For example, if you use a web browser, outbound HTTP connections
are permitted on port 80. Inbound responses from the Internet are allowed because
an outbound session is established.
When required, you can configure the SVG2500 firewall to allow inbound packets
without first establishing an outbound session. You also need to configure a port
forwarding entry on the
Advanced Port Forwarding Page or a DMZ client on the
Advanced DMZ Host Page .
