Connection not available with VPN and Lulu running on Big Sur #252

nnenci commented 4 years ago

Hi and thank you very much for this lovely and useful piece of software. I have updated to Bug Sur (no clean installation) and realized that Lulu creates a connection that appears among the Network connections on MacOS Settings. When Lulu is active and I turn on my IPSec VPN (I use the default system VPN Cisco IPSec service), the computer is not able to get any internet connection. Perhaps this one of mine is a silly question, but I have not figured out how to solve this problem. Any help would be very welcome. Thank you in advance. All best.

Same here, also upgrade (no clean install) to Big Sur but I had to remove the old LuLu Version to install 2.0. As soon as I connect to an IPSec VPN I am not able to use Microsoft Remote Desktop or even browse the web interface of an vCenter located in the corporate network. Thanks in advance!

I can confirm than Cisco IPSec VPNs are not working with Lulu 2.0.0 under Catalina.

I seem to have the same problem.

Can connect to NordVPN when Lulu is running. Can not connect to CiscoVPN (university) when Lulu is running.

MacOS Catalina 10.15.7 _ Lulu 2.2 just updated.

Thanks for the bug (reports).

tl;dr Apple bug, fixed by them in macOS 11.1

Unfortunately this an issue in Apple's Network Extension framework ...that affects any product/tool that leverages the framework :( From another vendor (that leveraged the Network Extension framework) :

"There is a bug in macOS ...where VPNs ... won’t work when a Network Extension is installed. This affects ... many other products based on Network Extensions. The VPN will connect successfully, but no data is transferred. The bug has been reported to Apple"

Apple has fixed this (and other Network Extension framework bugs) in macOS 11.1 ...so the (only?) solution is to update to latest version of Big Sur!

I’m running into the same problem: As long as LuLu is running I can’t connect to my University's IPSec VPN.

I work on my office PC remotely connected to it using the Microsoft Remote Desktop app on Mac. I was getting disconnected very frequently, almost every 1/2 hour to 1 hr. First I thought is from the firewall, but I checked with SonicWall and they said everything is fine and other users who use Windows don't get disconnected. I noticed that if I quit Lulu I could work long time, I wasn't getting disconnected, so it seems that the issue must be from Lulu on the Mac. Lulu version: 2.2.0 macOS version: 12.0.1 (Monterey) VPN client is SonicWall Mobile Connect, version 5.0.8 Microsoft Remote Desktop App version: 10.7.0
