UPnP Router Port Mapper

UPnP Router Port Mapper is a lightweight open-source Linux networking utility
for discovering UPnP Internet Gateway Device routers, inspecting active port
forwarding tables, and managing TCP and UDP port mappings. It provides an
accessible Linux alternative to PortMapper and UPnP PortMapper.

Features:
- Router Discovery and Active Mappings: discovers LAN routers via real SSDP
UDP M-SEARCH or custom gateway description links, queries external WAN IP
via SOAP, lists active port rules, and supports one-click rule removal.
- Add Forward Rule and Service Presets: creates TCP and UDP forward mappings
with auto-detected LAN IP, lease duration, and quick templates for SSH,
HTTP, HTTPS, Game RCON, and Minecraft.
- Port Reachability and Preset Backup: tests live local TCP connect latency
and port bind availability, plus JSON export and batch import of mapping
presets.

Disclaimer: This project is an independent open-source tool and is not
affiliated with, sponsored by, or endorsed by PortMapper or UPnP PortMapper.
