UTM 9 is blocking all traffic

cbasso
Hi,
I have virtual UTM 9 appliance that is working very well with this configuration
NIC 1 (Public IP)
NIC 2 (Public IP)
NIC 3 (Private IP)
Bridge1 = NIC 1 + NIC 2
With this configuration all work ok, I have some VMs with public IP behind Bridge1 and some VMs with private IP behind NIC3 (using NAT).

I have added a new NIC, because I need another separated private LAN.
After adding the new NIC,
all traffic from internet to the bridge1 or nic3 isn't working,
no log, nothing to understand why.
This occurs also if I switch on/off the new NIC.
If I remove the NIC (from the vm), I restart the firewall and all still work.
On the vmware host, the new NIC is a simple virtual nic not connected to physical nic (as NIC 3, that is working).

Why this? I'm still trying everything, but nothing works.

Any idea?
Thanks

    Hi, and welcome to the User BB!

    A simple diagram might make this clearer.  From what I understand now, I can only guess that the UTM perceives that it has two interfaces connected to the same Ethernet segment.

    Cheers - Bob
    PS If you search here, you will see that the preferred NIC is VMXNET3 and that the Flexible NICs cause problems.
