Web Filter You can either enable or disable these four filtering methods by
selecting Allow or Deny.
• Proxy If local users have access to WAN proxy servers, they may be able
to circumvent the Router’s content filters and access Internet sites
blocked by the Router. Denying Proxy will block access to any WAN
proxy servers.
• Java Java is a programming language for websites. If you deny Java, you
run the risk of not having access to Internet sites created using this pro-
gramming language.
• ActiveX ActiveX is a programming language for websites. If you deny
ActiveX, you run the risk of not having access to Internet sites created
using this programming language.
• Cookie A cookie is data stored on your PC and used by Internet sites
when you interact with them, so you may not want to deny cookies.
Block WAN Request
• By enabling the Block WAN Request feature, you can prevent your network
from being “pinged,” or detected, by other Internet users. The Block WAN
Request feature also reinforces your network security by hiding your net-
work ports. Both functions of the Block WAN Request feature make it more
difficult for outside users to access your network. This feature is enabled by
default. Select Disable to disable this feature. Then click the Apply button
and then the Continue button to save your changes.
Multicast Pass Through
• IP Multicasting occurs when a single data transmission is sent to multiple
recipients at the same time. Using this feature, the Router allows IP multi-
cast packets to be forwarded to the appropriate computers. Select Enable to
support the feature, or Disable to disable it.
IPSec Pass Through
• Internet Protocol Security (IPSec) is a suite of protocols used to implement
secure exchange of packets at the IP layer. To allow IPSec tunnels to pass
through the Router, IPSec Pass Through is enabled by default. To disable
IPSec Pass Through, click on Disable and then the Apply button. Click the
Continue button.
