Troubleshooting • Using Private Internet Access VPN and using Split Tunneling

0

I am using Private Internet Access VPN on a Raspberry Pi 4 with 64gb sd card. I want to use the split tunneling setting which says that it require kernel process events.

I chatted with their help desk and they said that their Split Tunnel requires the net_cls cgroup in order to work, which is not available on Raspberry Pi OS. If you can get net_cls cgroups working on Raspberry Pi (which you can install yourself) then Split Tunnel should work for you, too.

I used the following procedures and the setting for the feature is still grayed out.

To make net_cls cgroup work on your Raspberry Pi, follow these steps:

#Enable cgroups: #Edit the /boot/firmware/cmdline.txt file using your favorite text editor with root permissions.

sudo nano /boot/firmware/cmdline.txt

#Add the following parameters at the end of the line: #cgroup_enable=cpuset cgroup_enable=memory cgroup_memory=1 swapaccount=1

#Save the file and reboot your Raspberry Pi for the changes to take effect. #Check cgroups: #After rebooting, verify that cgroups are enabled by checking the /proc/cgroups file: #cat /proc/cgroups

#You should see the relevant subsystems (such as cpuset and memory) listed. #Create a new CGroup: #To use net_cls, create a new CGroup.

sudo mkdir /sys/fs/cgroup/net_cls

#Mount net_cls: #Mount the net_cls controller to the newly created CGroup:

sudo mount -t cgroup -o net_cls none /sys/fs/cgroup/net_cls

I completed these steps and still am unable to access this setting. I've attached a screenshot.

Thanks for your assistance
