The Security Tab - Firewall

Use this screen to enable or disable the Router’s firewall and various filters.

Firewall

Firewall Protection. This feature employs Stateful Packet Inspection (SPI) for a more detailed review of data packets entering your network environment. This feature is enabled by default. Select Disabled to disable this feature.

Block WAN Requests

Block Anonymous Requests. Check the box to enable this feature, so you can protect your network from being “pinged,” or detected, by other Internet users. This also reinforces your network security by hiding your network ports. Both functions of the Block Anonymous Requests feature make it more difficult for outside users to work their way into your network. This feature is enabled by default. Uncheck the box 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. Check the box to filter multicasting, or uncheck the box to disable this feature.

Filter Internet NAT Redirection. This feature uses port forwarding to block access to local servers from local networked computers. Check the box to filter Internet NAT redirection, or uncheck the box to disable this feature.

Filter IDENT (Port 113). This feature keeps port 113 from being scanned by devices outside of your local network. Check the box to filter port 113, or uncheck the box to disable this feature.

After you have made your changes, click the Save Settings button to apply your changes, or click the Cancel Changes button to cancel your changes.
