Comment (by arma):

 For a related ticket, check out #7875: the issue there is that if you want
 to listen on a low-numbered port (<1024), e.g. by doing port forwarding in
 iptables, there's no way to tell your Tor bridge to advertise that low-
 numbered port in your extrainfo descriptor. So you can listen there, but
 clients won't know to connect there.
