Site to Site OpenVPN - Unable to ping remote subnet from local LAN



  • Hey guys,

    I have set up an OpenVPN successfully on my pfsense. It is connected and I am getting a valid tunnel IP on both my pfsense box.

    I am able to ping remote subnet (remote LAN) from my pfsense box, but I am not able to ping remote LAN from my local LAN.

    Please find below my configuration.

    Local network Range - 10.0.1.1/24
    Remote network Range - 10.1.0.1/24
    Tunnel network range - 10.2.0.1/24

    As shown below I am able to ping the remote subnet from the client

    Ping to remote subnets fails from local LAN computers

    I have tried all possible things to fix this. Any help would be greatly appreciated. Thank you.



  • @Sebastian_IT said in Site to Site OpenVPN - Unable to ping remote subnet from local LAN:

    Local network Range - 10.0.1.1/24
    Remote network Range - 10.1.0.1/24
    Tunnel network range - 10.2.0.1/24

    No one of these is a network address! These are IP addresses.
    So edit you firewall rules and set correct network addresses as source and destination.

    BTW: In you firewall rule on server and client you have exactly the same address in source and destination. That doesn't make in sense at all.
