TEW-455APBO High Power Wireless Outdoor PoE Access Point
Active : Deny to drop and Pass to allow per filter rules
Interface : The interface that a filter rule applies
All packets are allowed by default. Deny rules could be added to the filter list to filter out unwanted packets and leave remaining allowed.
Click “Save” button to add IP filter rule. Total of 20 rules maximum allowed in the IP Filter List. All rules can be edited or removed from the List. Click Reboot button to activate your changes.
When you create rules in the IP Filter List, the prior rules maintain higher priority. To allow limited access from a subnet to a destination network manager needs to create allow rules first and followed by deny rules. So, if you just want one IP address to access the system via telnet from your subnet, not others, the Example 1 demonstrates it, not rules in the Example 2.
Example 1 : Create a higher priority rule to allow IP address 192.168.2.2 Telnet access from LAN port first, and deny Telnet access from remaining IP addresses in the same subnet.

Example 2 : All Telnet access to the system from the IP addresses of subnet 192.168.2.x works with the rule 1 of Example 2. The rule 2 won’t make any difference.
