NAT & Port Forwarding
Work through how address translation lets private networks share public addresses — and what breaks it.
Beginner
Static NAT basics
A one-to-one mapping gives a single internal server a fixed public address.
Intermediate
PAT / NAT overload
Share one public IP across many internal hosts using port numbers.
Advanced
NAT troubleshooting
Diagnose a misconfigured ACL that silently excludes a subnet from translation.
