This feature was once available on the VigorPro series routers such as VigorPro5500, VigorPro5510 and Vigor5300 series.

For other models, while DrayTek routers do prevent port-scans, Denial-of-Service (DoS) attacks, as well as having the ability to block web pages based on URL keywords and also block access to several content types, they do not offer virus or spyware protection such as scanning emails for viruses or checking web pages for advertising or spyware. We recommend that you have anti-virus and anti-spyware software installed on each of your computers, and keep them up-to-date.
