. Enable this feature to employ Stateful Packet Inspection (SPI) for more detailed review of
data packets entering your network environment.
Block WAN Requests
Block Anonymous Internet Requests
. Use this feature to 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 network ports. Both functions of the Block WAN Request feature make it more difficult for outside users to
work their way into your network. This feature is enabled by default. Remove the checkmark 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. This feature is enabled by default. Remove the checkmark to disable this feature.
Filter Internet NAT Redirection
. This feature uses port forwarding to block access to local servers from local
networked computers. Click the checkbox to filter Internet NAT redirection, or remove the checkmark to disable
this feature.
Filter IDENT (Port 113)
. This feature keeps port 113 from being scanned by devices outside of your local
network. This feature is enabled by default. Remove the checkmark to disable this feature.
