Working PiVPN/Wireguard now is dead, help!

maximumwarp · 17 March 2022 12:17

I use PiVPN with Wireguard on my Raspberry Pi Zero 2 W. Until the day before yesterday everything works like a charm but now if I connect to my VPN outside from the LAN I can’t navigate even if I try to visit 1.1.1.1.
I also use Pi-hole with Unbound that acts like DHCP and DNS server.
Installed Dietpi version 8.2.2, what’s happened?

are you sure your DDNS is up-to-date, pointing to your external IP address correctly?`

Do you see an actual handshake for your client? If I’m not mistaken, PiVPN is offer a command to view this.

I’ve static public IP address and I can connect correctly to VPN, but I can’t surf the web when connected or I can’t ping devices in LAN (the Pi too).

I don’t know how to check this…

And you can also check the log of your VPN client, maybe there is some hint in there.

At https://docs.pivpn.io/faq/ are also some useful tips for troubleshooting connection issues, but this can be a bit overwhelming for unexperienced users.

Unfortunately the WireGuard Client app will always show connected, even if it isn’t correct. Best is to have a look into your Client app. At least on my Android mobile phone, I could open/save the application loge file. Usually there you should be able to see if the VPN tunnel could be established or not. Unfortunately the WireGuard server did not offer such logs.

Seems that there are mutual handshakes so the connection is established.

I believe there should be wg show or something like that showing the last handshake. Apart from that, wireguard is very quiet and won’t maintain any unnecessary communication, unless it is for nat traversing.

for sake of testing, I connected my Android smartphone (Find-X2-Pro-di-Ivan) to VPN while it was connected to 5G… While connected to VPN it can’t navigate the web nor ping or connect to other devices in LAN.

make sure the phone tunnels everything to the Pi.
on the pi check for masquerade on eth interface, that ip_forwarding is enabled, and that nothing is blocking on the firewall.

maximumwarp · 18 March 2022 07:32

I’ve same problem on every device, not just for phone…
How can I check all these things, please?

trendy · 18 March 2022 09:27

Still, you need to verify that.
iptables-save -c; cat /proc/sys/net/ipv4/ip_forward

Joulinar · 18 March 2022 12:06

Usually it should be possible to access the DietPi device running PiVPN via IP address 10.6.0.1. Even if IP forwarding is not correctly set.

That is correct and there are hits on the firewall with the packets being NATed. You could run a packet capture to see what can be the issue:
apt update; apt install tcpdump; tcpdump -i wlan0 -evn host 8.8.4.4
Then start a ping from a WG client, or try to access from browser the page http://8.8.4.4

better to test with https://1.1.1.1/ instead of 8.8.4.4.

Anyway try to reach the VPN server (on VPN server IP 10.6.0.1) first, before going to try something on internet.

If I try to ping 10.6.0.1 from inside the LAN, I can reach the VPN server but if I try from outside the LAN the server doesn’t respond to ping.

ok let’s try it the other way around.

Switch your mobile phone to use mobile network
Activate WireGuard inside the app on your mobile phone
go to the PiVPN server
try to ping your mobile phone 10.6.0.2

is it working this way?

Btw: do you have just PiVPN installed or any other VPN solution in addition?

Done, no ping from server to client…
