      Hello
      I have openvpn site to site ssl/tls, between 4 sites with OPENVPN, and I want the 4 sites to see each other.
      For now, with site A, I can see B, C and D. (one server-client configuration for each site)

      But I want site B to see C and D.
      Site C, see B and D.
      And site D, see B and C.
      All this for the vpn.

      How can I this?

      Topology:
      10.1.0.0/16 - Site A - Server
      10.2.0.0/16 - Site B
      10.3.0.0/16 - Site C
      10.4.0.0/16 - Site D

      Thx

        You can achieve this by setting up client specific overrides, one for each client. VPN > OpenVPN > Client Specific Overrides.
        It is required that each client has a separate, unique certificate.

        Klick Add to set up a new CCO, enter the common name as it is set in the clients cert, assign an unique /30 tunnel subnet to each client, at "IPv4 Local Network/s" enter all the remote subnets the client should be able to access and at "IPv4 Remote Network/s" the subnet behind the respective client.

        In the client config also enter all remote subnets, which should be accessible in the "IPv4 Remote Network/s" box.
