DG834G Reference Manual You can specify one trusted user, which is a computer that will be exempt from blocking and logging. Since the trusted user will be identified by an IP address, you should configure that computer with a fixed IP address. 7. Click Apply to save your settings. Firewall Rules Firewall rules are used to block or allow specific traffic passing through from one side of the router 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 DG834G 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. You can change the order of precedence of rules so that the rule that applies most often will take effect first. See "Order of Precedence for Rules" on page 5-12 for more details.

Firewall Rules
Firewall rules are used to block or allow specific traffic passing through from one side of the router
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 DG834G 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.
You can change the order of precedence of rules so that the rule that applies most often will take
effect first. See
“Order of Precedence for Rules” on page 5-12
for more details.
