I am hoping to get some advice on how to achieve the following:
I have a video encoding device that essentially acts like an IP camera, in that you would normally plug it into an existing network over ethernet and access it through a web browser by entering its IP address on that network.
I want to connect this device to one of two ethernet ports on a computer running Ubuntu and have it accessible only by that computer on it's own network (with the encoder as the only device on the network besides the computer), then have that computer connected to another LAN through one of the other ethernet ports.
The purpose is to be able to have the computer stream the video feed to an AWS Kinesis account through the LAN, but not have the video encoder accessible directly on the same LAN, hopefully this will serve as a basic visualisation of what I have in mind.
[Video encoder]---(ethernet cable to Eth0)---[Ubuntu Computer]---(ethernet cable to Eth1)---[LAN router]
I apologise in advance for having probably under-described the scenario and am happy to elaborate more if needed. This would be a consequence of limited experience in both Linux systems and networking, neither of which I have had to work with much before, but am trying to learn through projects like this.
