There is any online server to host a middleman server for ssh tunneling? I don't have another computer with public IP to do that.
My scenario: I have two PCs, each one in a different network and behind NAT (thus, without a Public IP). I need to use a middleman server to make the ssh between the computers possible and I would like to have this service 24/7 a week, if possible, that's why I'm looking for any provider of this kind of service.
*In both cases, I'm not authorized to do port forwarding on the routers.
