Basic Guidance on Firewall Rules, Terminology and Symbols for a Beginner

I am trying to get used to the UTM using web interface and have no simple guide to the terminology and symbols.  For example on setting up a firewall rule, when an arrow points to "any" with a globe icon, does this mean any interface on the wan or does it include all interfaces including internal interfaces?

On an arrow there is sometimes a symbol which suggests a comment or something similar but not on all arrows.  This is true for red or green arrows.  What does this symbol mean?

Sorry to be so dumb but I would appreciate a basic manual reference which I can read on paper not on a screen.  Where may I find this in pdf form please?

  • Hello,
    don't know which arrows you mean...
    But:
    IP:ANY  means really ANY-IP - internal and external - and DMZ - and VPN - ...
    IP "Internet" means any IP behind an interface with default-gateway (WAN)
    Arrows:
    - green arrow stands for allowed
    - red stands for drop
    - yellow stands for reject (send a session reset to the source)
    If you need more/other information .. please use screenshots with comments to clarify your question
