The SBG6782 Firewall has various settings related to blocking or exclusively allowing different types of data through the Gateway from the WAN to the LAN. Even if specific web content is allowed on the computer level, it can be blocked on the router/gateway level using the firewall options.  By default, the Firewall is set at the Low level. This document describes how to configure the SBG6782 to filter specific types of web content.
