While the broadband users demand more bandwidth
for multimedia, interactive applications, or distance
learning, security has been always the most
concerned. The firewall of the Vigor router helps to
protect your local network against attack from

local network from accessing the Internet.
CSM is an abbreviation of Central Security Management
which is used to control IM/P2P usage, filter the web
content and URL content to reach a goal of security
management.
