Cannot Split Tunnel vpn with PIA

Hi guys,

I am new to Garuda and Arch and have had trouble with my VPN, Private internet access, and split-tunneling. I was using split tunneling on previous debian-based distros, both Mint and MX without issues.

Currently when I turn on split tunneling, and apply to all apps, it gives me an error that it could not configure DNS. When I first installed, stock settings allowed it to apply the vpn to everything. Once I turned on split tunneling it gave a generic error. Since then changed the DNS with garuda assistant which I was unable to turn off (setting Garuda Assistant > Settings > DNS to blank causes it to revert to the last selection, possible bug). Either way, before and after it has not worked.

When I turn VPN off for all apps, but select apps which are supposed to be subject to the VPN, it does nothing but does appear to connect successfully. Add an app to put behind vpn, it does not affect.

In PIA settings, I attempted it with default openvpn, i attempted it with the WireGuard option. Tried with UDP and TCP and with various different DNS options they offer including existing DNS.

I also deleted the app and reinstalled it, which nuked my settings and put me back at defaults. Still did not resolve.

As of now, I cannot even use the app with all stock settings without split tunneling to send everything through the VPN: it gets a DNS error likely from dns change in garuda assistant.

I wondered what additional information other than the inxi below I might provide that might help me track down the cause of this.

Garuda (2.6.3-2):
System install date:     2022-06-13
Last full system update: 2022-06-17 ↻
Is partially upgraded:   No
Relevant software:       NetworkManager
Windows dual boot:       Probably (Run as root to verify)
Snapshots:               Snapper
Failed units:

After you reboot, NetworkManager will write up a new /etc/resolv.conf for you which should resolve your DNS issue.

I have restarted many times while troubleshooting this after making changes, it has not made a difference.

Currently I see my Garuda Assistant DNS selection Cloudflare is still present in resolv.conf. I restarted against just now and PIA still cannot initiate default settings system-wide VPN. When I turn on split tunnel bypass all with exceptions, the exceptions still do not work. When I turn on split tunnel and tunnel only exceptions, it behaves as the system-wide vpn giving me a "Could not configure DNS" error.

Seems like networkmanager or something is locking down resolv.conf. I also noticed I could not modify it even as su.

Try removing the immutable attribute first:

sudo chattr -i /etc/resolv.conf

I think Garuda Assistant sets this attribute when you input a DNS preference, to prevent NetworkManager from overwriting it with the value it gets from the gateway.


Thanks for that info.

This does restore the original ability to use the VPN system-wide, but does not allow me to Bypass All apps except for exceptions. It does however allow me to apply Split tunnel with VPN to all (All Other Apps > Use VPN) and set specific Bypasses up (I think I failed here previously because I chose the wrong executable - my fault).

This is progress, but still not as I used PIA in the past. Applying a system-wide VPN is problematic because many applications or games have multiple files that you must create exceptions for. I much prefer tunneling everything except for specific apps.

Info about pia split tunnel:

edit: I did find while split tunneling was on with All Other Apps > Bypass VPN, those apps I subject to the VPN do work. Its just everything else that does not with a DNS address issue.

Its like something is preventing me from utilizing multiple DNS. Its either one or the other.

I'm not sure what your configuration is missing, but this page is worth a read through: Private Internet Access - ArchWiki

Crucially, it looks like IPv6 should be disabled as it is not supported by PIA. IPv6 support is built into the kernel, but you can disable the whole IPv6 stack with a kernel parameter:

sudo micro /etc/default/grub

Go down to the GRUB_CMDLINE_LINUX_DEFAULT= line and add ipv6.disable=1 in between the quotes (make sure you leave whatever options are already there :wink:).

Another consideration is it looks like getting the PIA DNS servers set up correctly may require some configuration. In this discussion a person hashed out a solution that looks like it might be worth a shot: Talk:Private Internet Access - ArchWiki

Setting PIA DNS

I was able to correctly configure this after doing more research about DNS and the way it is handled in general. I recommend looking at Domain name resolution, systemd-resolved, and NetworkManager for more information.

When using NetworkManager and systemd-resolved, you will need to install systemd-resolvconf.

Next, check /etc/NetworkManager/conf.d/dns.conf and ensure that systemd-resolved is enabled for dns like so:



Now to configure /etc/resolv.conf. In my case, I had messed things up by removing the symlink. We need to restore it so that systemd-resolved will work correctly. In order to do this, we have to first stop NetworkManager and PIA:

# systemctl stop NetworkManager # systemctl stop piavpn.service

Next, restore the symlink:

# rm -f /etc/resolv.conf # ln --symbolic /run/systemd/resolve/stub-resolv.conf /etc/resolv.conf

Finally, start NetworkManager and PIA again:

# systemctl start NetworkManager # systemctl start piavpn.service

Thanks for trying. I tried disabling the ipv6 but no go. Last solution doesn't seem to specifically address split tunnel and it looks like too many hoops to jump through. I will just put the janky extensions on my browsers and run anything else through a vm.
