I have a modem that has all the Ethernet ports used up. My isp only gives me one ip. I want to keep it at just having one ip.
One of the eth cables running from the modem goes to my dvr security camera system. From the location of the dvr, I ran a Ethernet cable to another building where I will set up a router.
The problem is how do I make that one Ethernet cord that goes to the dvr into 2 so that I can hook one Ethernet to the dvr and another running to the router?
I am thinking of using a unmanaged switch, but would that require me to get a second ip address from my isp? I really don’t want to do that. If that is the case, any suggestions what I can do?
