That's what I would put there. Get a small box PC, install Linux and setup firewall and ssh for connections from the internet. You can limit access from static IPs, etc. Searching for "minibox PC" or "miniITX PC" returns pages of small fanless computers with 2 Eth ports you can use to install Linux and setup routing. I see Intel® NUC are gaining popularity but I haven't seen one with 2 Eth ports yet. You probably need to use USB/eth converter to make a router. There is an excellent VPN like solution, shuttle. We use that in small company for remote connections to internal networks. As long as you can resolve the internal hostnames, or use IPs instead, you can connect to that network with any protocol. Network number needs to be different than what you have on LAN you are connecting from. I use that to connect to Cisco UCS Management (GUI) console and ssh to KVM and Openstack servers for example. Not sure what network speed you need but you can make very cheap router with SBCs like Raspberry Pi http://qcktech.blogspot.com/2012/08/raspberry-pi-as-router.html However, assuming you need this for industrial environment you would be better of with using small computers made for industrial use. Plenty of those around. > A GSM solution with AT&T would be ideal if they have sufficient coverage > since swapping out the 4G router would only require swapping the SIM > card instead of going through the ridiculous device activation routine > that Sprint and Verizon requires. Problem with a dedicated router in this case is that it's a dedicated box and not flexible enough for your use. With Linux box you can setup other things like active monitoring the environment (temp, light, switches, etc.) and perhaps send alerts in case of PLC related issues. > > I think that AT&T will be my next call.
