•POP3 (Post Office Protocol 3). A standard mail server commonly used on the Internet. It provides a message store that holds incoming e-mail until users log on and download it. POP3 is a simple system with little selectivity. All pending messages and attachments are downloaded at the same time. POP3 uses the SMTP messaging protocol.

•Specific Port#. You can add three additional applications by entering their respective port numbers in the Specific Port# fields.

Port-based QoS

Port-based QoS allows you to prioritize performance for four of the Router’s ports, LAN Ports 1-4. For each of these ports, select High priority or Low priority. If you select Disable, then QoS will be disabled for that port. The Router’s other four ports will be automatically assigned low priority.

Port-based QoS does not require support from your ISP because the prioritized ports are LAN ports going out to your network.
