Stateful inspection is a security feature that prevents unsolicited inbound access when NAT is disabled. You can configure UDP and TCP
Technical details are discussed in “Expert Mode” on page 39.
SSL Certificate Support
On selected models, you can also install a Secure Sockets Layer (SSL V3.0) certificate from a trusted Cer- tification Authority (CA) for authentication purposes. If this feature is available on your Gateway, an addi- tional link will appear in the Install page.
Netopia Embedded Software Version 7.7.4 uses SSL certificates for

VLANs
Motorola Netopia®'s VGx technology allows a single Motorola Netopia®
VGx was developed to ensure that subscribers receive the quality of voice, video, and data services they expect — to prevent a large data download from causing jittery video or poor voice quality. VGx achieves this goal by providing superior service segmentation and QoS features obtained by mapping multiple local virtual local area networks (VLANs) to one or more specific permanent virtual circuits (PVCs) for DSL, or wide area network VLANs for a fiber network.
Traffic prioritization is determined through the Institute of Electrical Engineering (IEEE) standard 802.1p, which specifies QoS algorithms to prioritize traffic based on protocol and source. This insures that each service receives the QoS treatment it requires; for example,
•video is free from latency,
•VoIP service is prioritized to insure aural quality, and
•data is securely and efficiently routed.
