Hello. I'm running LM 19. My work uses a PPTP VPN. I have a vpn connection setup through the network icon thingy on my taskbar. My networking works fine before connecting to the VPN, and even during the VPN session. When I disconnect from the VPN though, my DNS stops working. For example, after disconnecting I can ping 8.8.8.8, but not ping google.com. To solve the issue I've been using dhclient to get a new IP address from my home router, and then DNS starts working fine once again.
I'm not sure which logs I should look at or how to troubleshoot this issue. Any ideas/thoughts would be appreciated.

Re: DNS resolution fails after disconnecting from VPN
HI verge,
Not sure if this will help or not, but do you have the "resolvconf" and "dsnmasq" installed? Restart your computer afterward.
Hope this helps ...

Code: Select all
sudo apt install resolvconf dsnmasq easy-rsa

Re: DNS resolution fails after disconnecting from VPN
Is perhaps the Kill Switch and DNS protection enabled ??.

I see the same issue, and it was not happening on previous MINT version - I usually solve it by issuing dhclient <interface> but it is not very convenient
