I would like to install a webcam (better if an independent ethernet based object) at home, and access it from outside while I'm abroad, so I can check if there's mail. However, my internet connection at home provides me a dhcp address from an internal network. What kind of cam product and/or network trick can I use to securely access a webcam from outside ?
Edit: clarification. Unfortunately, I don't have any public IP address granted by my setup at home, so I cannot set up any port forwarding. From outside, I cannot access any machine that is connected to my ADSL router, simply because there's no internet IP to connect to. As far as I see, the only solution is to have the cam connect and send its stream to a server on the internet, whom I can connect to, and harvest this stream. Things like setting up a VPN are also a possibility.
I would like to know if there's a prepackaged product that allows this solution easily and without hassle.
Of course I have a public IP address, but it's the address of the NAT host, which is managed by my provider. – Stefano Borini – 2009-07-24T20:14:10.650
What you propose does not sound possible with my situation, as I only have a ADSL router that gives to the plugged in device a DHCP assigned internal IP address. I don't have any external address in my setup, except a personal website with ssh access I could use, but in any case I could not forward anything from this website to the private ip address I obtain at home. – Stefano Borini – 2009-07-22T21:50:07.850
You always have a public IP address (http://myip.dnsomatic.com). If it's not static, you can use DynDNS.
