VPN can only ping one way

  • Hi,

    I have the following setup:

    DDWRT Router (Client, - VPN Tunnel - PFsense (Server, I use PKI encryption for communication.

    Here are my PFsense (Server) settings:

    Local port: 1194
    Address pool:
    Local network:

    I have client to client VPN checked.

    The client is setup pretty much the same way and can also connect to the tunnel, it get's an IP adress of, which indicates that the tunnel should work fine, now here's where it get's weird.

    From the DDWRT router I can ping the PFSense and all the 192.168.16.x clients, but not the other way around. The firewall doesn't make any deny logs either. What could be my problem?

  • For a normal site-to-site connection i wouldn't use a PKI, but a PSK setup.

    If you really want to go the PKI way:
    Look at this howto: http://forum.pfsense.org/index.php/topic,12888.0.html

    From your description, i'd say you're missing a client specific config (iroute).

  • Hi, thanks for your answer. I edited the client specific config as you can see in the following image.

    In this image you can see my routing tables on the PFSense:

    These are the routing tables of my DD-WRT:

    I really can't see the problem…
