Accessing multiple networks from an Open VPN connection



  • Hi all,

    I am trying to figure out where in my configuration I have gone wrong. I am using 2.1.3-RELEASE (i386)

    Problem: I am able to ping and access all devices on the 192.168.2.1/24 network, but only 10.100.10.70 on the 10.100.10.71/24 network. I know there are other devices on the 10.100.10.71/24 network because i can ping them using the Diagnostic->ping option and if ssh into pfsense and open up a shell i can also ping the devices for ex: 10.100.10.103.

    Here is my setup:

    LAN (bridged) -> OPT1, OPT2, OPT4: Static IPv4 with DHCP server running (192.168.2.1/24)
    PRV5 (OPT3 originally): Static IPv4 (10.100.10.71/24). There is no gateway defined on this network

    I have setup the OpenVPN server and set the following

    IPv4 Local Network/s: 192.168.2.0/24,10.100.10.0/24

    I have also added the following rules on the PRV5 interface (if i remove the 10.0.8.0/24 rule i can't ping 10.100.10.70 either):

    ID Proto Source Port Destination Port Gateway Queue Schedule Description
            IPv4 * 10.100.10.0/24 * * * * none   Local Network passthrough
            IPv4 * 10.0.8.0/24 * * * * none   VPN Network passthrough

    I know the routes are okay at least on the client side, because once i connect from my windows box i have the following entries from "route print" command (note 192.168.2.0    255.255.255.0 and 10.100.10.0    255.255.255.0 ):

    I am at a loss on what might be causing this issue, any suggestions are greatly appreciated.

    thank you !



  • Hi,

    I have also added the following rules on the PRV5 interface

    you have to put the rule allowing traffic from OpenVPN to OpenVPN interface.
