Suppose I have a facility with a simple, flat, LAN on the 192.168.1.x subnet.
However, it has two Gateway devices (Sierra Wireless RV55 cell modems) - one at 192.168.1.1, and the other at 192.168.1.2.
I have a CPU on site that is configured at 192.168.1.3, and uses 192.168.1.1 as its Gateway.
However, I only have remote access to the cell modem at 192.168.1.2....so, I need to access the CPU at 1.3, but port forwarding in 1.2 won't work because the CPU is using the other Gateway.
I have asked Sierra if they support SSH tunneling, which I believe would work here, but they do not (only serial interfaces).
The Sierra does appear to support an OpenVPN tunnel - would that work here?
Open to other suggestions
