Firewall Rule "DROP" not working

 Good Morning,

I create the firewall rules to DROP packets from an interface to LAN interface but the DROP does not working.

 

 

Tha LAN_VOIP network doesn't must see the Internal Network and the DMZ network, and the same for the DMZ and Internal Network.

 

Why?

  • Ciao Davide, and welcome to the UTM Community!

    Several things for you to learn...

    Pinging is regulated on the 'ICMP' tab of 'Firewall'.  Disable 'Firewall forwards pings' and add Ping in the firewall ruleset.

    The "Any" Service only includes TCP and UDP.  Ping and other IP Protocols are not included.

    By default, all traffic is blocked, so your four firewall rules could be replaced by a single one:

    LAN VOIP (Network), Internal (Network) -> Any, Ping -> Internet : Allow

    You might be interested in a document I maintain that I make available to members of the UTM Community, "Configure HTTP Proxy for a Network of Guests."  If you would like me to send you this document, PM me your email address.  To see why, look at #2 in Rulz and also see Doug Foster's take on some of this: READ ME FIRST: UTM Architecture

    Cheers - Bob
