    [Workarounded] OpenVPN client static IP assignment


    I know in regular openvpn setup, you can use client-config-dir directive with file (where filename is the same as common name in the certificate) to specify static IP for specific common name. How do I do it via Web GUI in TomatoVPN? Is it possible? I am using version 1.25. Thanks in advance.

    I know that if you have a TAP setup, a MAC address will appear when your client connects. You can simply create a static dhcp entry in that case. I don't know about TUN all that much...Though the client-config-dir directive works. You just have to enable jffs2 and save it in /jffs so it doesn't get erased after a reboot.

    Ok. Just figure it out. It can't be done via the Web GUI directly. The Web GUI only supports iproute but not ifconfig-push under the Advanced tab of the OpenVPN Server configuration.

    Say I want to assign static ip to common name sc02 in my Server2 settings. I will do the following:

    Goto Administration->Scripts
    Select Firewall tab

    mkdir -p /etc/openvpn/server2/ccd/
    echo "ifconfig-push" > /etc/openvpn/server2/ccd/sc02
    Save and Reboot

    May be for next version of the TomatoVPN Web GUI, we can add support for ifconfig-push for client side static IP assignment. :D

    Anyway, 1.25 is really good. Loving it every minutes.
