NAT / PAT — Watch the Translation Table Build
Three inside hosts, one public IP, one outside server. Send a packet and watch R1 rewrite the source on the way out, build a translation-table entry, then untranslate the reply on the way back — for PAT (overload), static NAT, and a dynamic pool. Inject the classic misconfigs and see exactly where traffic dies.

PAT shares one Inside Global across hosts (told apart by port). Static NAT rows have no protocol/ports and never time out.
