Should there be a difference in latency when accessing resources by their public IP address versus their private, internal IP address? And if there is, would (mis)configuration be to blame?
My understanding (probably over-simplified) is the router will be smart enough to know that packets don't need to go out and back in when calling the public IP address and therefore there shouldn't be any performance hit.
Is that accurate?
Context: accessing a web server that is hosted on the internal LAN with a private address, but is accessible through the firewall via a public IP address on the WAN.
