Inbound Filter

When you use the Virtual Server, Port Forwarding, or Remote Administration features to open specific ports to traffic from the Internet, you
could be increasing the exposure of your LAN to cyber attacks from the Internet. In these cases, you can use Inbound Filters to limit that
exposure by specifying the IP addresses of internet hosts that you trust to access your LAN through the ports that you have opened.

Inbound Filters can be used for limiting access to a server on your network to a system or group of systems. Filter rules can be used with
Virtual Server, Gaming, or Remote Administration features.

Name

Specify a name for the inbound filter.

Action:

Select Allow or Deny from the drop-down list. This will apply the inbound filter rule on the WAN interface.

Remote IP Range:

Specify the remote IP address range and then click in the check box to enable the range.

Click on the

Save

button to store the changes.
