Inbound and Outbound Rules

You can use firewall rules to block or allow specific traffic passing through from one side to the

other. 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.

A firewall has two default rules, one for inbound traffic and one for outbound. The default rules of

the gateway are:

• Inbound: Block all access from outside except responses to requests from the LAN side.

Instructions for setting up inbound rules can be found in “Port Forwarding” on page 3-8

• Outbound: Allow all access from the LAN side to the outside. Use Port Blocking to set up

outbound rules (see “Port Blocking” on page 3-7).

You may define more rules that specify exceptions to the default rules. By adding custom rules,

you can block or allow access based on the service or application, source or destination IP

addresses, and time of day.
