Howto Block traffic between interfaces

rizzah
Hi,

I have an UTM with multiple network cards, I added a new DMZ. only thing this DMZ should be allowed it to have internet access and not able to receive anything on any of the other interfaces. However when I put up a server in this DMZ its able to ping the other interfaces and also the hosts in those networks. 

I have tried to make a big block rule to block anything from that network to any other network, but this didn't seem to solve the issue. Seems it has to be done by routing? 

If anyone could help me along that would be wonderfull.

    Ping is handled at the Firewall -> Advanced tab globally.

    You have to disable it there and create separate firewall rules instead.

    Thank you for your reply.

    I have tried this and disabled:

    Allow ICMP on Gateway
    Allow ICMP Through Gateway
    Gateway is Ping visable
    Ping from Gateway
    Gateway forwards pings

    And still i am able to ping from one host in a different vlan (interface) to another gateway address on the firewall and a windows client in another vlan.

    Anything elke i could be doing wrong?
