Private IPs can't ping public IPs (using 1:1 NAT)
-
We are currently running pfSense in 1:1 NAT mode. We have private IPs assigned to all of our servers, and the public IPs assigned to pfSense. Mapping and port forwarding is working perfect from outside of the network. We are only having one problem: If we try to ping one of our public IPs from one of the servers bound to a private IP we don't get a response. We can access all other Internet sites outside of our own public IPs from our servers with private IPs without any problems.
Any idea what this could be?

You can't do NAT reflection with 1:1 IPs on 1.2.3.
You can do it on 2.0 though.
You'll have to ensure that your local systems only access the servers by their private IPs.
