As I had same issue (willing) to connect 2 LANs over VPN, Netgear R7000 at home (central point) and OpenWRT router (at remote / holiday site).
The proposed "solution" (We do not support site to site OpenVPN configuration. The R7000 OpenVPN implementation is only for server to client configurations.) is absolutely NO solution !
After MANY tests, the TRUE solution is (as in many cases) that simple (at least one of them) ... - Configure Netgear VPN to access "Home Network only" - Configure both LAN with SAME IP subnet (and mask) - Ensure they don't have / share / assign same IP addresses (to avoid conflics) by : + Assigning differrent fixed IP@ + Defining non overlapping DCHP IP@ ranges + Same for static DHCP - Configure VPN in Brigde mode - Block (filter) DCHP traffic (to avoid one side providing IP @ to other) And you're in business ! You can acces resources / devices on other LAN at Layer 3 (IP@) or Layer 2 (DLNA, ...) and in both directions !
