Firewall Protection
The router provides firewall security using Stateful Packet Inspection (SPI) and hacker attack logging for Denial of Service (DoS) attack protection. SPI inspects the contents of all incoming packet headers before deciding which packets are allowed to pass through. Access control is provided with packet filtering based on port and source/destination MAC/IP addresses. With Virtual Server Mapping, only specific services on a local server, like web, FTP or games may be made accessible from the Internet, ensuring the rest of the machine remains protected from hackers. VPN pass-through is provided to let mobile users securely access office files and mail from home.

Quality of Service Features
The DSL-2740B supports multiple priority queues to enable a group of home or office users to experience smooth connectivity without suffering the effects of network congestion. This support for Quality of Service (QoS) allows you to enjoy lag-free transmission for applications such as VoIP and streaming multimedia over the Internet.
