• Multicast Pass-through—When enabled, the router allows IP Multicast
traffic to come in from the Internet. The default is Disable.
• SIP Application Layer Gateway—When enabled, the SIP Application Layer
Gateway (ALG) allows Session Initiation Protocol (SIP) packets (used for
Voice over IP) to traverse the NAT firewall. This feature can be disabled if the
VoIP service provider is using other NAT traversal solutions such as STUN,
TURN, and ICE.
• Block—Select the Web features that you wish to restrict. All those features
could place security concern to your personal computers on the LAN side.
You have to balance your needs on those applications and security. The
default is unselected.
- 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
programming language.
- Cookies—A cookie is data stored on your personal computer and used
by Internet sites when you interact with them, so you may not want to
deny cookies.
- ActiveX—ActiveX is a Microsoft (Internet Explorer) programming
language for websites. If you deny ActiveX, you run the risk of not having
access to Internet sites using this programming language. Also, Windows
Update uses ActiveX, so if this is blocked, Windows Update does not
work.
- Access to Proxy HTTP Server—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 blocks
access to any WAN proxy servers.
