Will double NAT not have any latency issue?
One question, I would like to understand the following sentence, which appears on the "Firewall: NAT: Outbound" page.
"With advanced outbound NAT disabled, a mapping is automatically created for each interface's subnet (except WAN)."
Since I haven't enabled NAT at all yet, pfSense is supposed to be generating the necessary mappings. However, pfSense is not supposed to be creating mappings for the WAN interface (as stated in the quoted sentence). But then, how come I can access the Internet via the WAN interface?
That's the only interface where I currently require NAT to function.
By the way, I don't have a router "in front of me". The pfSense firewall is actually "in front of me" and is acting as a router/firewall.
Note that 10.0.2.0/16 and 10.0.3.0/16 are the same subnet 10.0.0.0/16.
Also, I'm not using a DMZ. Hence, I couldn't really grasp what you meant by "Using the DMZ IP for the pfSense WAN forwards everything to the pfSense and you have full controll there.". Can you please elaborate?
