Configure a Filter Rule-IP Filters
You can limit access to the WAN from PCs on your LAN, or limit access from the WAN to your LAN using filter rules that can be configured on your UT-300R2 ADSL router. The UT-300R2 router will examine incoming and outgoing packets to determine if they meet the requirements you specify in the Filter rule, and then either Allow or Deny access based upon the rule you have configured. These rules can be based on IP addresses, MAC addresses, URLs, Domain names, and TCP/UDP port numbers. In addition, you can specify a rule to apply to packets from your LAN to the WAN (Internet), from the WAN to your LAN, or both.
To configure a filter rule, click on the Filter button under the Advanced tab. This will open the Filters page, as shown below.
