How can I recover my original DNS after Forticlient Linux disconnect?

[alohl66987]

Hi, after updating to forticlient 7.0, when I disconnect from my vpn, my ubuntu do not recovers its original dns configuration while in the older version it did it perfect. Could I reconfigure anything to recover this option to avoid reconfigure manually my DNS in every disconetion?

Hello @alohl66987 ,

As per my research, the issue you are facing was a known issue. As mentioned below and the fix is available on the following releases.

714338 FortiClient does not revert DNS setting after OS suspend while VPN is connected

0711970 While FCT is connected to EMS and VPN tunnel is disconnected the DNS entries in /etc/resollv.conf are not removed

These are fixed in FortiClient versions 6.4.7, and 7.0.3.
