MikroTik same network on location A and B double NAT - how to solve

RouterOS General
1

Good day,

I have on location A - 192.168.0.0/24
on location B - 192.168.0.0/24

On site A, for example, I have a printer at 192.168.0.5
At site B, I have a server with an accounting system of 192.168.0.5

When I’m at location A and I want to connect to location B VPN - which has its own range - 10.10.10.0/24, I connect, but I can only see everything that is in location B and I lose connection with everything on A.

How to make sure that this is not the case? What needs to be added? I read something about double natu, but I don’t know how to do it.

Thank you.

Change IP range on one of both sites.
It will make your life a lot easier.

Doesn’t really help to resolve the IP conflicts which are going to be created.

@ holvoetn,

don’t worry, your proposal was totally correct - to change the remote subnets. so @op network will be scalable in the future.

while my proposal was options - promoting MT own bridging vpn protocols :+1:t2: maybe vxlan as well :wink:

so now, let us give the @op a time to think about which solution will fit to his condition. :wink:

The proper way to sort this is to change the IP range of 1 or both of the sites. However, you might be able to cheat using something like Tailscale or Zerotier.
Businesses should be on 10.X networks, homes are usually on 192.168.X networks… and this usually make life a LOT easier down the road when you need to deploy VPNS and need to add more sites.

What kind of VPN are you using??
