> Yes indeed, I have come across such a beast. In theory it should be possible
> (they have predefined ports for "World of Warcraft" etc) but it does not work.
> It's a Telefonica Movistar Homestation, OEM is ADB Broadband Italia. I found
> the docs for both companies and the ADB ones say it does do it but it's not
> available on the firmware Telefonica Movistar ship. I managed to find an OEM
> hidden-page where I can get at the actual firmware (looks like a stripped
> down DD-WRT to me) but a port-forward option is missing.
> The router supports FTP, SSH, and Telnet; but no amount of name/password
> guessing could get me in.
> I was expecting many issues but this had me stumped on the last day.
> This leaves me with a RasPi in a foreign country that I can't easily SSH into
> because some ass-hat knobbled a basic feature of a router that even the
> cheapest, nastiest things support out-of-the-box.
> Is there any way for me to somehow get the RasPi to punch-out from the
> remote LAN and give me SSH access?
> Something about SSH reverse-proxy is rattling around the dusty corridors of
> my mind, but I've never done such a thing.
> I can do a screen share to a Windows box where I installed Cygwin, so I can
> access the Pi that way to set things up.
