Block WAN Requests

The Block Anonymous Internet Requests is a feature is designed to prevent intruders from attacking through the Internet. When it is Enabled, the Router will drop both the unaccepted TCP request and ICMP packets from the Internet. The hacker will not find the Router by pinging the Internet IP address. Click Disabled to allow those packets to get through.

IP Multicast occurs when a single data transmission is sent to multiple recipients at the same time. Using Filter Multicast feature, the Router allows IP multicast packets to be forwarded to the appropriate computers. Select Enabled to filter the feature, or Disabled to allow it to pass through.

Filter Internet NAT Redirection option allows you to block local users behind the router to gain access to the local server that is behind the same router by using the Internet IP address. To enable this option, select Enabled. To disable this option and allow local computers to get access to the local server, select Disabled.
