I am using VMware ESXi to create a network with a test domain running Exchange 2007.
I'm using pfSense as the firewall between my physical network (which I am using as the WAN) and the VM internal network (which isn't connected to physical ports) which is the test domain's LAN.
Everything is working fine. The LAN is using
192.168.1.x addresses and I am routing traffic through our network which is
Users on our network are now getting security alerts in Outlook for the test Exchange server (currently they show as for mail.contoso.com as I haven't configured Exchange).
I need external mail access to this test domain so that I can prove failover techniques but I'd like to block the other network users seeing the domain.
Currently I can ping the firewall and servers on our
62.x network from my VMs too (not so much of a problem but it would be nice if these were blocked from each other).
What rules can I set in pfSense to prevent this?
