Ok, this is a real Newbie question. I don't even know what I don't know. So I may not be even asking a valid question.
Can the RPi be set up to use P2P (instead of Port Forwarding) to connect to it over the Internet via SSH, SSL, OpenVPN, etc?
I see security cameras that use P2P for direct access over the internet without having to open router ports. Can the same be done with the RPi under Raspbian?
Do you have to have a service/server somewhere to make the P2P connection?
Please point me to some resources/web pages where I can learn how to do this.
