Firewall 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 DG632 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 can 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. To access the rules configuration of the DG632, click the Firewall Rules link on the main menu, then click Add for either an Outbound or Inbound Service. Using Router Mode 6-15

Firewall 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 DG632 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 can 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.
To access the rules configuration of the DG632, click the Firewall Rules link on the main menu,
then click Add for either an Outbound or Inbound Service.
