13 tor-fw-helper - Manage upstream firewall/NAT devices
17 **tor-fw-helper** [-h|--help] [-T|--test] [-v|--verbose] [-g|--fetch-public-ip]

23 **tor-fw-helper** currently supports Apple's NAT-PMP protocol and the UPnP
24 standard for TCP port mapping. It is written as the reference implementation of
25 tor-fw-helper-spec.txt and conforms to that loose plugin API. If your network
26 supports either NAT-PMP or UPnP, tor-fw-helper will attempt to automatically
27 map the required TCP ports for Tor's Or and Dir ports. +
31 **-h** or **--help**::

41 **-g** or **--fetch-public-ip**::
42 Fetch the the public ip address for each supported NAT helper method.
44 **-p** or **--forward-port** __external_port__:__internal_port__::
45 Forward external_port to internal_port.
49 This probably doesn't run on Windows. That's not a big issue, since we don't
50 really want to deal with Windows before October 2010 anyway.
