Firewall rules: network or interfaces?

[BriyasTaramya]

In the context of firewall rules, could you clarify whether the terms "Internet," "LAN," and "Guest" refer to the networks themselves or the interfaces facing those networks? Apologies if it seems like a simple question, but I seek a detailed explanation to ensure a clear understanding.

With your example, don’t think of a web request from inside your LAN as just one thing, but multiple steps. Each step along the way would fall into one of the different rule omegle voojio classifications.
