Is it possible to add another subnet to a VPN?

Question

VPN

There is a VPN channel between two offices 10.0.0.0\24 and 10.0.1.0\24. In two offices, devices appear from a different subnet 192.168.0.1 in one office and 192.168.0.2 in the second office. Is it possible for these devices to communicate with each other using this VPN.
Routers are everywhere Cisco.

Answer 1

It is possible, the most simple to register static routing. Most likely you have an error in the description in the case of networks 192.168. these are 2 single devices and not a network of devices, write correctly with masks, then you can advise more specifically.

Answer 2

If I understand correctly, there are two devices in different offices 192.168.0.1 and 192.168.0.2 (I assume that they have the same subnet mask - 255.255.255.0) with the main addressing 10.0.0.0/24 and 10.0.1.0/24 respectively. And you need these 2 devices to communicate with each other.
If these 2 devices should only communicate with each other and there is no one else with them and are connected via managed switches, then you can select them into a separate VLAN and use L2TP in your case, work with subinterfaces) combine them into a broadcast domain - as if they were connected to the same switch.
A variant with the use of static NAT is possible - then these devices will be disguised as "normal" addresses for offices (for example, 10.0.0.1 and 10.0.1.2) and can communicate in the same way as all other devices in the offices.
if you specify why the devices should have exactly such addresses and also with whom else these 2 tricky devices should have a connection - you can be more specific :)
