I have a Windows 7 PC that is currently connected directly to a gas pump thru a modem, we are upgrading and will soon be needing to connect the new gas pump to a switch that only routes things like NVR's, Alarm panels, Access control panels that have no access to the internet. The PC is joined to our Domain and has access to the internet so I was wondering if I could just install an additional NIC card to the PC to connect to the pump instead of having to run a new cable from the pump to the switch and how I would configure the extra card to connect to the pump without it having access to the internet. Any utility device having internet capabilities is a no no with the IT Dept. Any help with this is appreciated.
2I don't think you understand IP networking at all... Plus your PC is an immediate "no no" since it connects to the Internet, by your own requirements. Do the job right the first time, run the cable and properly connect the device, no matter how you try to figure this out, if you company network and "other" network are separate your running a cable anyway so do it correctly the first time. – acejavelin – 2017-12-16T05:22:46.230
Your right acejavelin I know very little about networking that's why I posted here. The PC and pump are now connected with a Cat5 cable but only utilizing only 2 pair for the modem. The switch is quite a distance from the PC and will be moved further in the near future so I'm trying to save myself some work. I was hoping to isolate the pump from internet access by creating a subnet that has no internet access on the second card but maybe that can't be done. Thanks for you response. – Panrider – 2017-12-16T06:01:31.410
Since you are in the Luck of having an IT-Department your best option would be to ask one of them to help you and not here since they know their Network while everyone here can just make good guesses. Also every IT-Team has its own way of how they like things to be connected and configures so any as good meant instruction from here may still be not the correct way in their Eyes – konqui – 2017-12-16T08:19:07.357
Thanks for your response Konqui our IT team definitely has their ways so I may very well have to just run my cable to the switch and experiment later. – Panrider – 2017-12-16T16:02:33.937
Issues specific to corporate IT support and networks are off topic, see On-Topic. Please talk to your IT department.
