I have some knowledge of networking but not much, so I appreciate knowing from the experts.
modified part I have 10 devices(PLCs) with the same IP address "192.168.42.2" that I want to connect to one router(192.168.47.1). This network(2) has no internet connection and to have access to systems I have to change the IP address of my PC to connect to the gateway of network2. I have set the VLAN port of the network2 to be able to connect to the network1 with the gateway IP "192.168.1.1". In the network1 I have internet access. But the problem is that just one host can be connected to this router with its IP. Another host with the same IP can not be connected to the Lan port of this router(I thought maybe there are ways that I do not know). Then I thought of using the MAC address as a unique identifier. But I could not use this technique. I converted the LAN to VLAN but again the same issue, I realized that the second host with the IP (192.168.47.2) can not be accepted by the same router, whether it is connected to LAN or VLAN. end of modified part
The router here is used to expand another Network "192.168.1.1" and make the connection between the two networks (1 and 2). For this purpose in the setting of the router, one Ethernet port is configured as Vlan with the IP address of "192.168.1.2".
My problem is :
