IP Address Filtering Help

The IP Address Filtering feature allows you to control Internet Access by specific users on your LAN based on their IP addresses. To disable the IP Address Filtering feature, keep the default setting, Disabled.

To set up an IP Address Filtering entry, click Enable Firewall and Enable IP Address Filtering on the Firewall page, and click the Add New… button, and then follow these instructions:

  1. Effective Time - Enter a range of time in HHMM format, which points to the range time for the entry to take effect. For example, 0803 - 1705, the entry will take effect frome 08:03 to 17:05.
  2. LAN IP Address - Enter a LAN IP address or a range of LAN IP addresses in the field, in dotted-decimal notation format. For example, 192.168.1.20 - 192.168.1.30. Keep the field open, which means all LAN IP addresses have been put into the field.
  3. LAN Port - Enter a LAN Port or a range of LAN ports in the field. For example, 1030 - 2000. Keep the field open, which means all LAN ports have been put into the field.
  4. WAN IP Address - Enter a WAN IP address or a range of WAN IP addresses in the field, in dotted-decimal notation format. For example, 61.145.238.6 - 61.145.238.47. Keep the field open, which means all WAN IP addresses have been put into the field.
  5. WAN Port - Enter a WAN port or a range of WAN ports in the field. For example, 25 - 110. Keep the field open, which means all WAN ports have been put into the field.
  6. Protocol - Select which protocol is to be used, either TCP, UDP, or All (all protocols supported by the router).
  7. Action - Select either Allow or Deny through the router.
  8. Status - Select Enabled or Disabled for this entry on the Status pull-down list.

To add another entries, repeat steps 1~9.

You should specify the following IP address filtering table:

ID Effective Time LAN IP LAN Port WAN IP WAN Port Protocol Action Status
1 0800-2100 192.168.1.7

25 All Deny Enabled
2 0800-2100 192.168.1.7
