Details

This is a tor-fw-helper rewrite in Go that functions as a drop in replacement for the original C code.

Features:

Limitations:

go-fw-helper's "-T" option does not write to the log file.
As the helper needs to be able to receive UDP packets, the local firewall's config may need to be altered.
Lease times are hardcoded to "0" for UPnP (Indefinite/1 week depending on the UPnP version) and 7200 seconds for NAT-PMP. RFC 6886 includes dire warnings about broken UPnP implementations that freak out for non-"0" lease times.

TODO:

Maybe also support PCP. Technically everything that speaks PCP should also speak NAT-PMP, so this is relatively low priority.
