Manual NAT vs Double NAT: The Measurable Reality

This episode dives into the mechanics of manual outbound NAT in OPNsense and the measurable reality of double NAT latency. We trace what happens at the packet level when you switch from automatic to manual mode, explain why hybrid mode is the safest starting point, and cut through the forum mythology to reveal how much latency double NAT actually costs versus other network issues like bufferbloat.
