Note: Bridge Firewall Rules is available only in DSR Octeon models.
A firewall is a security mechanism to selectively block or allow certain types of traffic in accordance with rules
specified by network administrators. You can use this page to manage the firewall rules that control traffic
between interfaces of your Bridged network.
The List of Bridge Firewall Rules table includes all firewall rules for the bridged network and allows several
operations on the firewall rules. By default in Bridge Mode, all access is allowed for Inbound and Outbound
direction between the interfaces of the bridged network. Inbound Rules govern access from DMZ Port to the
LAN Port1 interface. Outbound rules restrict access to traffic leaving your LAN Port1 interface. Firewall rules are
applied in the order listed. As a general rule, you should move the strictest rules (those with the most specific
services or addresses) to the top of the list.
To create a new bridge firewall rule:
