How to change the subnet of a device without access to it?

Question

System administration

Hello, I have 5 network interfaces (rndis modems, android modem), each has an interface of 192.168.42.100-120, but because of subnet 42 they do not work correctly, how can I separate them through additional software so that they work stably? Type to make a redirect:
Interface 1 - 192.168.42.101 to 192.168.101.101
Interface 2 - 192.168.42.122 to 192.168.102.122
Interface 3 - 192.168.42.108 to 192.168.103.108
And so on
. and each device has its own virtual machine and virtual adapter, by any chance there is no ready-made software for this?
