Using the miniupnpd upnpc utility, the author demonstrates how to add, list, and delete port mappings via UPnP. Key caveats covered include router firmware inconsistencies, the need for UPnP to be enabled, and a quirk where ports below 1024 fail silently when the UPnP service runs without root privileges. A working test using socat and telnet confirms the technique. NAT-PMP and PCP are briefly mentioned as alternatives, though both suffer from similar implementation issues. ## Full article daily.dev links to this article rather than hosting it.
