Make LAN from other site to site VPN accesible to clients conn. to different VPN

[Porfavor]

Hello,

I have setup two VPN servers on my opnsense (at a remote location). One is a peer-to-peer VPN where the remote network is my home LAN. This works well.

Moreover, I setup a second server for remote access. It is possible to connect to this server and reach the actual local LAN. Though, I cannot reach the home LAN through it. I entered this network into Local IPv4 network within the server settings.

What else do I have to do? Or isn't this possible?

For each VPN you need to configure routing for all remote subnets to go via OPNsense. If your three networks are A, B and C then devices on each need to have a route to the other two. If the VPN is hosted on the default gateway for a network, then you only need to set up the routing there. If it isn't, you need to push out static routes to the clients; either through the VPN config file or through DHCP. or at a last resort by setting them on each device.

Remember that packets need to travel both ways; from the sender to the destination and replies back the same route. Each hop along each path needs to know how to reach both ends.

Thank you for your reply.

The situation is as follows:

- Mobile Device (let's call this network C) connects to OPNsense on network B. Network B is connected to network A via different OpenVPN Server / Peer to Peer. I want to reach network A from network C.
- Network A has a router in between network B and network A's OPNsense.
- I have set a route on the router of network A regarding VPN-network of the access server as I did with the VPN-Network from network B of the site to site server.
- I haven't set any custom routes on network B's OPNsense.
- There does exist a route (on OPNsense network B) to networks A's LAN via the OPNsense on network A.

How can I achieve this? Set a route at System -> Routes -> Configuration? If so, I am not sure how to do this.
