2. LAN-to-LAN OpenVPN
The branch office establishes a OpenVPN tunnel with head office to connect two private networks
over the Internet. The routers are installed in the head office and branch office accordingly.
Configured in this way, head office and branch office can access each other.
Both office LAN networks must be in different subnets with the LAN-to-LAN application.
Note:
Server side: Head Office
Set up parameters (WAN interface, port, tunnel virtual subnet IP/mask, encryption, authentication,

etc) on OpenVPN server side.
