Prevent WAN access on additional IP address.

spacemancw
To map a public address to an internal address in the UTM-9, my understanding is that under "Interfaces" > "Additional Addresses" > I add a new address and assign it to the Outside interface.

Then create a NAT that for instance maps ANY service coming from ANY source going to this Additional address gets translated to the internal address that I choose.

My problem is that now I can manage the firewall using the additional address.
For instance, if the WAN address of the UTM is 65.65.65.60 and the additional address is 65.65.65.70, I can now managed the UTM using:

https://65.65.65.60:4444/ and https://65.65.65.70:4444/


How do I prevent https://65.65.65.70:4444/ form working.

I tried firewall rules such as, traffic from ANY using service 4444,80,443 going to 65.65.65.70, drop or reject. But it doesn't change anything.

Any help would be appreciated.

    Hi ThorstenS, thanks for the reply. Unfortunately that is not where the issue lies.
    The Allowed networks tell us what Sources are allowed to manage the firewall. I have this locked down to our offices, it's not ANY.
    The issue is really the opposite of this, it's the "destination" that is allowed to be managed that I'm trying to control.
