connect three LAN's with Open VPN keeping addressation, and client acting as server(?)

nowakom

Hello,
is it possible to configure OpenVPN this way:

LAN1 (behind NAT, no public IP, not accessible form internet, only reverse SSH tunnel aviable, network addr: 10.0.0.0/24), router with LEDE 17 and OpenVPN Client - this host initiates whole VPN, other machines (mostly Debian) without OpenVPN Clients, IP cameras, NAS.
LAN2 (behind NAT, public IP, accessible from internet, network addr: 10.1.1.0/24). Router with LEDE 17 and OpenVPN Server listening for LAN1 router incomming connection, one Debian file/db/www server not accessible from internet.
LAN3* mobile clients Debian/macOS/Android etc. with OpenVPN Client.

How to set this up to be visible as one LAN with 10.0.0.0/24 addressation with all hosts able to comunicate each other?
I mean: when I am phisically at LAN1 (not usung OVPNClent) I can access any host at LAN2 using 10.0.0.x, and any mobile host from LAN3. When I'm mobile, I can access LAN1 and LAN2 with 10.0.0.x etc.

yes it is possible. but you can make things easier by using slightly different addresses. you did not say what addresses LAN3 uses. is there a NAT on LAN3?

Skaperen: LAN3 is 10.0.0.0/8 and it's also behind NAT.
