How to access other lan inside lan


  • Hi,

    I'm not getting over how to access other lan inside lan with OpenVPN.

    I have added IPv4 Local Network/s: 10.8.64.0/19 to the OpenVPN

    I need to access network 10.222.222.0/24 which can be accessed from 10.8.64.0/19. I can access servers from network 10.8.64.0/19 with OpenVPN but not servers in network 10.222.222.0/24. I have the interface for network 10.8.64.0/19 on my firewall.

    You need to push a route to 10.222.222.0/24 out to the VPN client.

    You need to make sure traffic from your VPN clients to 10.222.222.0/24 is allowed by your OpenVPN firewall rules.

    You also need to be sure the hosts on 10.222.222.0/24 will route traffic for the OpenVPN clients back to the right place.

    Adding 10.222.222.0/24 to the local networks in your OpenVPN server should be enough, though there might be a better way to do it like pushing the route using a client-specific attribute.


  • I think we need more details.  Site to site or road warrior?  Provide a network map and post our configs.


  • If it is site-to-site, then, in the Remote Network/s box at both client and server end, list all the remote networks reachable across the VPN link. (i.e. the list will be "opposite" on client to server)

    If it is road warrior server, then put all the networks reachable through the server into the Local Network/s box - this will tell the clients what they can reach across their link to the server.

    In all cases put rules on OpenVPN to allow traffic from the clients to the various networks. Put rules on the server-end LAN etc to allow traffic from the server network/s to the clients (if you want traffic to be initiated in that direction also)
