Yosemite VPN (PPTP) issue

I also can not get PPTP to work.

I have my machine running DHCP, but the IP is assigned by the router as a fixed address based on the MAC address of the connection.

Our GlobalProtect VPN is also not working, so I've lost all VPN connectivity to work.

You are absolutely right. For years I have connected to my office via VPN wo issue using static IP at my home network. Changed to DHCP and it works. Clearly a programming gilt's that Apple should correct although I have been relating this issue for 6 weeks on the beta site

When using a static IP address and manual entries for subnet and router in the network settings, Yosemite VPN fails to stay connected. This is probably a bug or an error that Apple needs to fix.

When having the client computer (the one you are using) network settings configured to either just use DHCP or DHCP with manual address, the VPN connections (both L2TP and PPTP) work. If using ARD to access computers on the local network, the results are better if you select "Send all traffic over VPN connection" under advanced options for the VPN connection.

Same problem here. I hope Apple could fix it ASAP.

And I found that PPTP is still OK using WiFi. Just the ethernet part is broken.

No only PPTP, IPSec VPN also needs DHCP to work properly.

Try to use for the Ethernet card the DHCP with manual address.

You mean I should use an ethernet card?

I tried both Belkin Thunderbolt Express Dock and Apple Ethernet Adapter(Thunderbolt). Neither worked.

So I don't think the ethernet card matters.

Using the ethernet service WITHOUT IPv4 being set to configure by DHCP results in VPN not being able to connect. Getting an ethernet card is not likely to resolve the issue - Apple needs to fix the problem with its code.

As an interim workaround to use VPN, you can either set the ethernet connection configured to use DHCP (with or without using a manual address for the machine), or connect using wi-fi to VPN. To connect using wi-fi, in Network preferences set the Service Order so that wi-fi is listed first in the list. Alternatively, set up an alternative Location under Network preferences so that only wi-fi or ethernet configured by DHCP and then switch back and forth between your normal settings and the interim DHCP or wi-fi only location.

I have been using GlobalProtect on my mac, since I upgraded to Yosemite I cannot use that anymore. None of your solutions work for me, any ideas?

Thanks.

I think you should wait for a patch or quick fix from Apple.

I also use GlobalProtect at our university, and that stopped working as yours did.

Finally got PPTP working over ethernet, by routing all traffic through the VPN connection.

David, would you please let me know how I can do that? thanks.

I am also using ethernet but still cannot make global protect work. What else do I need to do? connect through PPTP VPN and then connect to GlobalProtect?

Even if it does not solve the problem but I can explain why GlobalConnect does not work.

The reason is, that pangpd.kext is not compatible with the new 10.10 kernel. We will need an updated version of Global Protect with an pangpd.kext that is compiled against the latest kernel. I already asked my ip help desk to provide me with a new version

From PanGPS.log:

/Applications/GlobalProtect.app/Contents/Resources/pangpd.kext failed to load - (libkern/kext) not loadable (reason unspecified); check the system/kernel logs for errors or try kextutil(8).

Hope that makes waiting a little bit easier

I can confirm that I have similar issues with VPN connectivity. I'm trying to tether trough my iPad and when I start the CiscoAnyConnect I can see that it connects, builds the tunnel, but then it tears it down and it throws a weird error.

I have to say that if I am on any regular WiFi connection I can VPN with no problem. What it appears to me that this is an issue on how the tethering device (in my case iPad) and the laptop with Yosemite OS X are handling the connection. I've talked to our network guys and we were looking at the firewall logs and there was an event that was saying something sort of 3G/4G connection can't be established based on PPPExtended (I can't remember the exact words). What it looked like, and how my counterpart explained to me is that once the VPN tunnel is built, it appears that it can’t install the LAN subnet routes on the tunnel interface (assuming on my laptop), and then the connection gets dismantled.

Clearly this looks like an Yosemite issue while tethering with another iOS device with 8.1.
