Quick question, and this might seem kinda stupid.
I have 2 Interfaces with Public Addresses (External, DMZ) and behind the DMZ is a couple of Servers with Public IPs.
I have created the following firewall rules:
Allow: Internal -> Any
Allow: DMZ -> External
Allow: External -> DMZ (HTTP, HTTPS, etc)
When I am setting up IPS, is there any advantage changing the protected Interface to ANY since webmin and user portal are available on the External Network? I understand this is redundant for Interfaces with Private IPs, but is it for External Interfaces with Public IPs?
My current IPS protected Interfaces are:
DMZ
Internal
Any help would be greatly appreciated.
Thanks,
Kyle
