node-portmapper

Library that maps ports on NAT-enabled routers with the protocols UPnP-IGD and NAT-PMP

TODO

• UPnP-IGD support
• NAT-PMP support
• auto renewal if lease expires
• unmap when process terminates
• listen to external ip changes
• what todo when there are multiple nat devices?
  • should probably only change the configured gateway
  • quit after first successful mapping or map port through all protocols?
