Asante Technologies VR2004 user manual LAN Filter Settings

3.5 Filter Settings

Filter Settings give you additional control over what users on your local network can see on the Internet, or what users on the Internet can connect to on your local network. LAN filters control what re- sources on the Internet your local users can connect to. WAN filters allow extra control (beyond what the built-in firewall provides) over what users on the Internet can see on your local network.

LAN and WAN filters may be enabled separately. By default they are both disabled. Both the LAN and the WAN filters have a default policy—either to allow all traffic or to block all traffic. After configur- ing the defaults you can then add rules that make exceptions to the default.

3.5.1 LAN Filter Settings

Since the router’s primary purpose is to allow several computers to share an Internet connection, most users will configure a LAN filter to allow all access. But you may want to restrict some users on your LAN so that they don’t have complete access to the Internet.

For example, you may want to keep some of your users from using Usenet. Usenet uses NNTP (Network News Transfer Protocol) which runs on port 119.
