VPN not working after upgrading to Mavericks

VPN is not functional in the current release of Mavericks. There is an beta update 10.9.1 that has been released to developers that contains the VPN fix. Please see attached.

Hi! I had same problem with VPN (PPTP) mavericks

1. archive the racoon file

2. replace the racoon file from previously system (downloaded from any website)

3. still not working

4. replace the archived racoon back (mavericks)

5. change permission (sudo chmod 555 /usr/sbin/racoon)

6. oups.... VPN now working........

why? i dont know.

good luck.

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

It seems that the original link for racoon.tar.gz posted by dave.h is gone.

So for those who did update without a backed up racoon.tar.gz you can get it here:

With the racoon fix I now have a working MacBook Pro and my wifes iPhone. But no chances for my Android KitKat to work from remote. :-( On the local network it works though...

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.

I replaced the usr/sbin/racoon file from the previous version on my time machine (march 11, 2013) and it worked.

Ha! Yes! Deleting that file solved my issue. I'm sure it came from the FIOS tuneup I once did

So far this is my only Mavericks problem and it's solved.

Thanks for both the detailed advice and the specific instructions to navigate the finder to get there.

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.

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)

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!

Now we are talking! This is the fix I have been awaiting. Tested using cellular network and all is good.

Update is working for me. Now I'm ready for the equivalent iOS update 🙂
