We have some devices connected together through a switch. We need to access them through another network, but because of limitations in available IP addresses, we can't get an IP address from that network.
Q: How to access my devices through an external network? What kind of device should be used?
As routers are suggested, I have made some search and found that there is two scenario: sending from local to remote, sending from remote to local, the later is more difficult to me because the remote have only router ip as its dest address, and to send to the right local computer, the only choice is Port Forwarding?
