Block WAN Requests
Use these features to enhance your network's security and filter multicasting.
Block Anonymous Internet Requests. This keeps your network from being "pinged" or detected and
reinforces your network security by hiding your network ports, so it is more difficult for intruders to work their
way into your network. Select Enabled to block anonymous Internet requests, or select Disabled to allow
anonymous Internet requests.
Filter Multicast. Multicasting allows for multiple transmissions to specific recipients at the same time. If
multicasting is permitted, then the Router will allow IP multicast packets to be forwarded to the appropriate
computers. Select Enabled to filter multicasting, or select Disabled to allow multicasting.
Filter Internet NAT Redirection. This feature uses port forwarding to block access to local servers from local
networked computers. Select Enabled to filter Internet NAT redirection, or select Disabled to allow Internet NAT
redirection.
Filter IDENT (Port 113). This feature keeps port 113 from being scanned by devices outside of your local
network. Select Enabled to filter port 113, or select Disabled to allow port 113 to be scanned.
