    Hello,

    I am running OS X version 10.10.5 and OS X Server version 4.1.5.

    I have set up the VPN to use L2TP. I use 192.168.xxx.1 through 175 for all local and wireless devices and I have reserved 10 addresses for the VPN clients starting at 192.168.xxx.200.

    It connects just fine, but as soon as I try to send traffic through it, meaning try to browse any webpage, it times out and disconnects. I can see the client sending data, but it never receives any back.

    I can't figure out why.

    On the client I have the L2TP service configured as follows:
    Options:
    All options are set.
    Disconnect when switching users
    Disconnect when user logs out
    Send all traffic over VPN connection
    TCP/IP:
    Configure IPv4: Using PPP
    Configure IPv6: Automatically
    DNS Servers:
    10.0.0.1
    Proxies:
    None

    Please see the log below from one of the attempts I have made not too long ago. I have masked IP addresses and names.
