Firewall

SPI Firewall Protection

Enable this feature to employ Stateful Packet Inspection (SPI) for more detailed review of data packets entering your network environment.

Internet Filters

Filter Anonymous Internet Requests

When enabled, this feature keeps your network from being "pinged", or detected, by other Internet users. It also reinforces your network security by hiding your network ports. Both functions of this feature make it more difficult for outside users to work their way into your network. This feature is enabled by default. 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 Disabled to disable this feature.

 

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 Disabled to disable this feature.

 

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 Disabled to disable this feature
