I wondered if anyone can suggest a free tool that will allow me to connect to my home development machine, which is behind a NAT'ed firewall owned by my ISP through a server that I lease that is on the public internet.
That is, right now I can't ping my home machine at all, because it's double-NAT'ed, so no matter how many holes I poke in my home firewall, I can't get to it.
I have a server in a datacenter that I could run some sort of "proxy" on, if there was a tool I could install on my home machine that would ping the server occasionally and check for a request to open a channel or something...
Obviously it can be done, since tools like GotoMyPC and Fog Creek's Copilot can do this. I'm just looking for a free alternative.
That way, I could connect to my home dev machine if I'm at a coffee shop somewhere and want to get to files from my laptop.
