I have two raspberries in two sites. Both have OpenVPN running and some clients connected.
First site, let's say A, has a LAN 192.168.1.0/24. Second site, let's say B, has 192.168.26.0/24.
I would like to connect these two sites with a VPN, no matter which one. My first idea was one of them as a OpenVPN client from de other one, but I can not change OpenVPN addressing 10.8.0.0/24......and this create a conflict.
So, is there any way to change OpenVPN addressing? Changing server parameter on server.conf results just in changing IP pool, but not tun0 interface.
Do you recommend a second VPN technology like IPSec/IKE? Maybe Wireguard?
Thank you very much!
