Good evening,
Our environment utilizes a single subnet, single vlan (unmanaged) network. We have a Sonicwall NSA 240 series firewall. All vmhosts connect to this fw via two unmanaged switches.
Currently, our external resources (FTP, SMTP, FTP, HTTP\S) are managed through NAT Policies, and port access through Access Rules.
I was wondering if configuring an interface as a DMZ zone using Transparent IP mode would be more secure. I am not familiar with this setup, so feedback and suggestions would be greatly appreciated.
