  • Hello,

    Did you try to setup a firewall rule that say : 

    source : internal network
    service: internet browsing
    destination : any
    action : block

    and then create the same rule but source create a group with allowed IPs and action Allow.

    that will be the first thing that come to my mind.

  • Hi, shinichix, and welcome to the User BB!

    Is this a home-use license?  If not, then do you have a paid subscription for Web Protection?

    To associate specific machines to specific IPs, look in 'Network Services >> DHCP' on the 'IPv4 Lease' tab where you can make IP assignments static based on the MAC address.

    When you did the initial installation you probably already have a rule like 'Internal (Network) -> Web Surfing -> Internet : Allow'.  If you have "Any" in that, replace it with "Internet" as I've indicated.  Replace "Internal (Network)" with "Internet Allowed" to restrict internet access to only the members of the group.

    Since all traffic is dropped by default unless explicitly allowed, you don't need the following block rule recommended by Flo, but it would keep the Firewall log file smaller and "cleaner."

    Cheers - Bob

  • Hi Bob... I'm attempting the same thing on a home-use license - latest firmware 

     

    If I created a rule in the FW:

    Position: 4

    Sources: Internet allowed (all my mac assigned, dhcp hosts)

    Services: Web Surfing

    Destinations: Internet IPv4

    Action: Allow

     

    ... what would be the cause for my devices still having internet access once disabling that rule?

  • Hi, and welcome to the UTM Community!

    The hint in my post above was asking if he had a Web Protection subscription.  See #2 in Rulz.

    Cheers - Bob
