User can decide to enable this firewall function including Packet Filter, Block Hacker Attack, and Block
WAN request features for better security control or not. But be noted, it wastes network processor
computation power. The performance will be lower about 10% to 15%. More firewall features will be
added continually, please visit our web site to download latest firmware.
3.4.3.5.1 Packet Filtering
Packet filtering function enables you to configure your router to check specified internal/external user (IP
address) from Internet access, or you can disable specific service request (Port number) to /from
Internet. This configuration program allows you to set up different filter rules up to 6 for different users
based on their IP addresses or their network Port number. The relationship among all filters is “or”
operation, which means the device checks these different filter rules one by one, stating from the first rule.
As long as one of the rules is satisfied, the specified action will be taken.
