Overview of Rules to Block or Allow Specific Kinds of
Traffic
• Outbound Rules (Service Blocking)
• Inbound Rules (Port Forwarding)
• Order of Precedence for Rules
Firewall rules are used to block or allow specific traffic passing through from one side to the
other. You can configure up to 800 firewall rules on the wireless VPN firewall (see the
following table). Inbound rules (WAN to LAN) restrict access by outsiders to private
resources, selectively allowing only specific outside users to access specific resources.
Outbound rules (LAN to WAN) determine what outside resources local users can have
access to.
