Firewall Tab - Access Rules
Access Rules evaluate network traffic to decide whether or not it is allowed to pass through the Router’s firewall.
Access Rules look specifically at a data transmission’s source IP address, destination IP address, and IP protocol
type, and you can apply each Access Rule according to a different schedule.
With the use of custom rules, it is possible to disable all firewall protection or block all access to the Internet, so
use extreme caution when creating or deleting Access Rules.
The Router has the following Default Rules:
•
All traffic from the LAN to the WAN is allowed.
•
All traffic from the WAN to the LAN is denied.
Custom rules can be created to override the above Default Rules, but there are four additional default rules that
will be always active and cannot be overridden by any custom rules.
•
HTTP service from the LAN to the Router is always allowed.
•
DHCP service from the LAN is always allowed.
•
DNS service from the LAN is always allowed.
•
Ping service from the LAN to the Router is always allowed.
Access Rules
Except for the Default Rules, all configured Access Rules are listed in the Access Rules table, and you can set the
priority for each custom rule. The Access Rules table lists the following information for each Access Rule: Priority,
Enable status, Action, Service, Source Interface, Source, Destination, Time, and Day. Click the

an Access Rule, and click the

per page, select a different number from the
entries per page
drop-down menu.
