Tor's (little) Firewall Helper specification
|
||||
Jacob Appelbaum
|
||||
|
||||
0. Preface
|
||||
|
||||
This document describes issues faced by Tor users who are behind NAT devices
|
||||
and wish to share their resources with the rest of the Tor network. It also
|
||||
explains a possible solution for some NAT devices.
|
||||
|
||||
1. Overview
|
||||
|
||||
Tor users often wish to relay traffic for the Tor network and their upstream
|
||||
firewall thwarts their attempted generosity. Automatic port forwarding
|
||||
configuration for many consumer NAT devices is often available with two common
|
||||
protocols NAT-PMP[0] and UPnP[1].
|
||||
|
||||
2. Implementation
|
||||
|
||||
tor-fw-helper is a program that implements basic port forwarding requests; it
|
||||
may be used alone or called from Tor itself.
|
||||
|
||||
2.1 Output format
|
||||
|
||||
When tor-fw-helper has completed the requested action successfully, it will
|
||||
report the following message to standard output:
|
||||
|
||||
tor-fw-helper: SUCCESS
|
||||
|
||||
If tor-fw-helper was unable to complete the requested action successfully, it
|
||||
will report the following message to standard error:
|
||||
|
||||
tor-fw-helper: FAILURE
|
||||
|
||||
All informational messages are printed to standard output; all error messages
|
||||
are printed to standard error.
|
||||
|
||||
3. Security Concerns
|
||||
|
||||
It is probably best to hand configure port forwarding and in the process, we
|
||||
suggest disabling NAT-PMP and/or UPnP.
