VPN not working after upgrading to Mavericks

Anyone else having issues? It worked fine with Mountain Lion on my iMac but, after updating to Mavericks today, it won't connect. It says to verify the server's IP number but it's correct.


Thanks,

iMac, OS X Mavericks (10.9)

Server.app 3.0.1 hasn't fixed this problem.


It's remarkable how many on this thread are still using PPTP, which has been completely broken for over a year and should be considered unencrypted. <https://www.cloudcracker.com/blog/2012/07/29/cracking-ms-chap-v2/> <https://www.schneier.com/blog/archives/2012/08/breaking_micros.html>


Disable OS X Server's PPTP VPN now, whether PPTP "works" or not.


OpenVPN works fine with Mavericks, and its TLS-based authentication is much more secure than OS X Server's L2TP/Ipsec-PSK. <https://discussions.apple.com/thread/5538749?answerId=23898306022#23898306022>

If you're holding out for L2TP VPN to work in 10.9.1, I've got bad news. It's still not fixed!


If you've previously replaced racoon in /usr/sbin with a 10.8.X version, be sure to make a copy of the file before upgrading to 10.9.1. The upgrade will over-write the old file with what appears to be the same version of racoon as we had in 10.9.0.


Rolling back to an old 10.8.X version of racoon "fixed" L2TP VPN

Dec 18, 2013 11:50 AM in response to NEI

Had a working L2TP VPN from an external network by replacing 10.9 racoon with 10.8 racoon. My experience is that when I installed the 10.9.1 update, /usr/sbin/racoon was replaced and that broke my L2TP VPN connection from an external network. I reinstalled the 10.8 version to /usr/sbin/racoon and have L2TP VPN working from an external network again.


So my experience is that the 10.9.1 update does not fix the VPN problem and will reinstall the broken version of racoon.

So, I upgraded all my machines to 10.9.1, including the Mavericks server. L2TP now works internally for me, but it does not seem to be working externally. I have UDP ports (public and private) set to: 500, 1701, 4500 and TCP ports set to: 1723.


I wonder if 10.9.1 changed an external port setting?


Are others VPN'ing in externally with L2TP using Mavericks (not modifying with the Mountain Lion Raccoon) 10.9.1 now? Or is it still broke?


How has it gone for you?

10.9.1's racoon file was not fixed which is why others in this thread re-applied their ML racoon file. So, Maverick's racoon file in 10.9.1 still won't allow L2TP VPN externally. PPTP still works fine for network accounts externally.

Apple just released a patch downloadable via the App store to solve the issue. They point to a KB article which is not found when you click on it: http://support.apple.com/kb/HT6080.


More information at http://www.macrumors.com/2013/12/19/apple-releases-software-update-for-vpn-issue s-on-mavericks-server/?utm_source=osx&utm_medium=push&utm_campaign=mac


Now the question is, did Apple really solve the problem? Mine is not working while I did not change anything to the OS like the Racoon tips. What is your opinion?


(Anyway, I am downgrading to Mountain Lion because all my Ubuntu VM's in Fusion are randomly crashing after upgrade to Maverick)

Dec 19, 2013 1:54 PM in response to Xibel NL

Yes, this latest patch fixed it. I had two folks test it externally, and all is good. I even went as far as turning off PPTP on the server gui and they were both able to connect in with the L2TP protocol.


I am running standard Mavericks 10.9.1 with server 3.01 and the new VPN patch that was just released (no Mountain Lion Raccoon transplant).


All good now!
