Rules

Firewall rules are used 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 FR328S are:

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

• Outbound: Allow all access from the LAN side to the outside.

You may define additional rules that will 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. You can also choose to log traffic that matches or does not match the

rule you have defined.
