Comment (by yawning):

 Replying to [comment:5 ioerror]:
 > One of the reasons that we wrote tor-fw-helper was to have NAT-PMP
 support. It is a very simple protocol. It would really be a shame if after
 all these years, we simply returned to what we had with Vidalia many years
 ago.

 Indeed, the protocol is simple.  Which is why it says "not supported
 '''yet'''".  I could have blindly plugged in the random third party
 library and said "well, this should work on Linux, but I haven't tested
 it", but I didn't because that would be a shitty thing to do.  What would
 be even more of a shame is if "Yawning hasn't bought a base station,
 installed a FreeBSD VM, written/tested the `PF_ROUTE` code, blindly
 written the Windows `GetIpForwardTable()` code and found a victim to test
 it, '''yet'''" stalled things indefinitely or kept me from posting about
 progress.
