1. About IP Filter Feature

If this feature is used, SD-300/SD-310AN allows accesses only from the registered IP address ranges.
Up to 4 IP address ranges can be specified.



2. IP Filter Settings

IP filter settings can be configured from the Web page.
The example below shows how to allow communications only from the IP address range "172.25.72.10" - "172.25.72.20":

Access the Web page of SD-300/SD-310AN.


In the left pane of the Web page, click IP Filter.


Enter the Starting Address and Ending Address and click Add (up to 4 address ranges can be registered).
In this example, 172.25.72.10 is entered as the start address and 172.25.72.20 is entered as the end address to allow communication from that range.

  • If the address range is deleted which includes the IP address of the computer which is currently accessing SD-300/SD-310AN, the communication for that computer will be lost. It will not recover until the IP filer feature is disabled.

  • By deleting all the registered address ranges from Manage Configured Ranges, you can disable the IP filter feature as well as allow accesses from all IP addresses.

To take effect of the changes, restart SD-300/SD-310AN by clicking Restart from the left pane of the Web page.

  • If you are to continue configuration on the other pages, you do not have to restart SD-300/SD-310AN. Restart it when all configuration is done.
