I need to be able to access an IP camera that is on the same local network as a raspberry. I do not have access from the outside because it is a mobile data network that does not give me public IP or I can do NAT. I was thinking of creating a ssh reverse tunnel against a server on internet (Virtual Private Server). I would like that from any internet PC could put a domain with a port and redirected me to the web that is serving the IP camera, and this should be through the raspberry.
I was testing with iptables and ssh reverse tunnel but although the local port fordwaring works, the reverse tunnel didn't. I've tried with
sysctl net.ipv4.ip_forward=1 sudo iptables -t nat -A PREROUTING -p tcp --dport 1111 -j DNAT --to-destination 192.168.1.192:80 sudo iptables -t nat -A PREROUTING -p tcp --dport 1111 -j DNAT --to-destination 192.168.1.192:80 ssh -f -N -T -R22222:localhost:1111 [email protected]
Nothing happens if I try with http://myvps.com:22222
Thank you very much
