I was asking about the S2S VPN lately, but have a bit different question now. What are the industry standards / best practices to securely connect two company branches? I was thinking of a VPN connection, but it does not allow one to connect two identical subnets e.g. 10.11.12.0/24 with 10.11.12.0/24. Is there a way to connect two offices via VPN and reduce or eliminate the possibility of subnet overlap?
