Configuring PFSense to exclude specific external ip address
id flag

Pfsense is installed on top of five dedicated servers, NAT rules are already defined and everything works fine. Now, I want to have one of the external IP addresses to be ignored by pfsense gateway. In other words, for that IP, there is no Pfsense installed, no address translation is done, no internal IP exists, etc.
