Hello, I am using a set-up of a modem going to multiple devices via LAN with assigned IP addresses. I would like to remotely access the devices (ping the devices remotely) that are connected to the modem without interrupting the LAN communication currently existing. Is there anyway to establish a secondary network that will not affect the current communication with the devices and allow me to ping them remotely via installing a router or some other means?

Thank you,

I'm trying to ping the devices from outside the network in order to remotely access monitoring devices within the network. So the solution would be to forward ports for each of the devices using a router? If there is currently a modem connection with no router to the devices would putting a router after the modem change current IP addresses and interrupt communication on the LAN?

My end goal is to remotely monitor metering devices currently on a LAN network from anywhere. The metering devices communicate with each other on the LAN and cannot have any interruption of service. So my goal is to get remote access to them without altering the current LAN communication of the metering devices. They currently get internet from a modem which i'm not sure if it has a router or not. My question is if it is possible to achieve connection with these devices externally by placing something additional into the network without affecting their current communication?
