Windows users + firewalls having trouble with automatic port selection

We've been seeing a lot of complaints from Windows users with firewalls who experience apparently random behavior in whether their tor in TBB connects successfully. It gets to Bootstrapped 100%: Done and then doesn't do anything else.

After some minor experimentation -- having them turn off (or uninstall) their firewall, and having one revert the TBB settings back to pre-auto days -- I think Windows and firewalls simply can't handle the automatic port selection very well. Tor will connect to an open port (I think) and then not actually be able to send traffic. Since it doesn't connect to the network, but doesn't obviously error, users just wait and get frustrated.

velope had an idea on IRC that there could be a client version of reachability testing for local ports.

Can you explain more about what works and what doesn't here? Is it 'ControlPort auto' that is at issue? 'SocksPort auto'? Clients shouldn't be opening other ports IIUC -- or is this for relays?

I have seen two reports of 'TBB doesn't work' from Comodo Firewall users today, and velope said that he had seen other reports that TBB didn't work with Comodo Firewall running.

16:36 < velope> separately, it appears comodo blocks software launched from usb from opening any port.

Switching this to a 'bundles' bug. I opened #3948 for a fix that could be done on the Tor side, and that I think would also resolve this ticket.

Resolution: fixed
Status: newclosed

This is fixed in the windows bundles as the auto port feature is disabled there now.
