Unified Services Router User Manual Figure 46: List of Available Application Rules showing 4 unique rules The application rule status page will list any active rules, i.e. incoming ports that are being triggered based on outbound requests from a defined outgoing port. 5.8 Web Content Filtering The gateway offers some standard web filtering options to allow the admin to easily create internet access policies between the secure LAN and insecure WAN. Instead of creating policies based on the type of traffic (as is the case when using firewall rules), web based content itself can be used to determine if traffic is allowed or dropped. 5.8.1 Content Filtering Advanced > Website Filter > Content Filtering Content filtering must be enabled to configure and use the subsequent features (list of Trusted Domains, filtering on Blocked Keywords, etc.). Proxy servers, which can be used to circumvent certain firewall rules and thus a potential security gap, can be blocked for all LAN devices. Java applets can be prevented from being downloaded from internet sites, and similarly the gateway can prevent ActiveX controls from being downloaded via Internet Explorer. For added security cookies, which typically contain session information, can be blocked as well for all devices on the private network. 78
