The Protocol Filter allows you to filter traffic based on protocol type. The app uses deep packet inspection (DPI) and machine learning provided by the Netify Protocol Detection Engine to classify over 160 different protocols, including:
RDP and VNC
PPTP, IPsec and OpenVPN
and many more
If your system does not have this app available, you can install it via the Marketplace.
You can find this feature in the menu system at the following location:
Gateway » Filtering » Protocol Filter
Navigate to the Protocol Filter in your Webconfig interface. By default, there should be no rules and the service should be running:
Manipulating the Service
By default the service is running. If the service is running and you would like to stop it, Click the 'Stop' button on the right. To start it if stopped, press the 'Start' button in the same location. You can also uninstall this app from this location as well as leaving a review of how you like it.
Configure Filtered Active Protocols
To modify the blocked protocols in the filter, click the 'Edit' button in the Active Protocols section. Select the protocols that you wish to block and deselect protocols that you wish to permit.
White List Protocol Access for Certain Users
You can allow specific IP addresses to bypass the Protocol blocks altogether. To add an exempted IP, click the 'Add' button in the 'White List' section. Type the IP address in the field provided and click 'Add'.
The whitelist feature is most useful if the LAN
devices you want to whitelist have Static IP's or you use Static Leases in the DHCP Server
