NAT Checks for Reliable Network Troubleshooting

Network failures are often blamed on DNS or firewall rules, but NAT behavior can be just as important. A lightweight NAT check helps confirm whether a client is behind address translation and whether a service is reachable as expected.

A practical workflow is simple: record the local network context, compare the observed public address, and test the target port from the same environment. This separates application problems from routing and translation issues.

Good diagnostics are small, repeatable, and easy to share.
