Paywall
A paywall is a method of restricting access to content via a paid subscription. Beginning in the mid-2010s, newspapers started implementing paywalls on their websites as a way to increase revenue after years of decline in paid print readership and advertising revenue. In academics, research papers are often subject to a paywall and are available via academic libraries that subscribe.

With Endian these are differentiated by their color coding:The Endian Firewall includes support for load balancing, which means you can add another connection to the Internet from the red network; Endian Firewall then distributes the network load on both interfaces.
