Demystifying NAT Traversal with STUN TURN and ICE
Feb 1, 2023 · The native transport IP address of the client is called the host address (Address A in the figure); the IP address and UDP port as seen by the TURN server after NAT has been applied is called the server reflexive address (Address B in the figure), and the endpoint-mapped address on the TURN server is called the relayed address (address C).

NAT Lab - Cisco Learning Network
This is what I added R1 "ip nat outside source static 128.10.10.2 10.1.40.1" R2 "ip nat outside source static 128.10.10.1 10.1.10.1" Static NAT is used to do a "one-to-one mapping" between an inside address (internal) and an outside address (external). Static NAT also allows connections from an outside host to an inside host.

Applying NAT using Layer 3 Switch - Cisco Learning Network
Hello Team, I would like to use a Layer 3 switch as my gateway between my LAN and the ISP. I discovered that much as you can configure an IP address on the physical interface of a switch when it is running on Layer 3 mode, you cannot apply command of " IP nat inside" or "IP nat outside" on the Interface configuration mode.
