IP conflict with VPN

VPN
1

I have a self hosted VPN at home (WireGuard). When I connect to a different router and activate the VPN, I cannot access my services I host at home. The problem is that both routers use the same 192.168.1.x range.

I use NginxProxyManager to access the services (they are just pointing to 192.168.1.x IPs). I don’t want (can’t) change the settings on the new router, and I would prefer to avoid changing the device’s settings (as the device is owned by someone who doesn’t understand much about VPNs).

What solutions do I have?

Changing the IP address would be the easiest and correct solution, but if that’s impossible, NAT would seem to be your only option. In general, having two devices with the same address is a bad idea.
