PIA OpenVPN connects successfully but no internet connection

Hello,

I'm trying to set up the PIA VPN on my Arch laptop; the OpenVPN log says it connects successfully, however I'm unable to ping or access any external ip / domain.

I've tried using NetworkManager + openVPN + private-internet-access-vpn AUR package to automate the process but that doesn't work either. I'm currently just using the OpenVPN cli to simply things:

sudo openvpn UK\ Southampton.ovpn

The openvpn config file is stock from the PIA website:

resolv-retry infinite

crl-verify crl.rsa.2048.pem

disable-occ

It sounds like there is some routing issue, but i'm not too sure how to go about debugging it
ip route without VPN:

default via 192.168.1.254 dev wlp3s0 src 192.168.1.151 metric 303 
192.168.1.0/24 dev wlp3s0 proto kernel scope link src 192.168.1.151 metric 303 

ip route with VPN:

0.0.0.0/1 via 10.25.10.5 dev tun0 
default via 192.168.1.254 dev wlp3s0 src 192.168.1.151 metric 303 
10.25.10.1 via 10.25.10.5 dev tun0 
10.25.10.5 dev tun0 proto kernel scope link src 10.25.10.6 
10.25.10.5 dev tun0 proto kernel scope link src 10.25.10.6 metric 450 
31.24.226.244 via 192.168.1.254 dev wlp3s0 
128.0.0.0/1 via 10.25.10.5 dev tun0 
192.168.1.0/24 dev wlp3s0 proto kernel scope link src 192.168.1.151 metric 303 

I don't quite understand too much about what I'm looking at here so the issue may be obvious.
It should be noted that I'm able to the use Free ProtonVPN ovpn config just fine - this connects successfully and my internet works just fine. Additionally, PIA works correctly on my android device on the same network so I can't see this being an issue with my local network / home router.

Thanks for looking!

Re: PIA OpenVPN connects successfully but no internet connection

Hi.

Can you please post your routes with protonvpn up? I think i have the same problem.

I can add that when vpn is up i cannot ping anything but vpn provider gateway (and my local tun ip of course).

Re: PIA OpenVPN connects successfully but no internet connection

What i've done:
1. installed linux-lts
2. disabled ipv6 in my wired connection in nm
3. reboot using old linux-zen (not newly installed linux-lts)
4. internet is working (through openvpn)

wtf?!

All routes are the same (from first post, mine when it's not working, mine when it's working).

Hello

The Same problem here - https://bbs.archlinux.org/viewtopic.php?id=232290 , probably latest linux-lts commit.
