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 the IP addresses and names.
