Ubuntu VPN DNS resolution problem.

Last Updated 5 months ago

If internal resources are accessible when the VPN is connected, but internet access is no longer working, upgrade FortiClient VPN. The issue was present in version 7.2.1.0700 and is solved in version 7.2.2.0753.

To upgrade, excute the following commands:

wget -P /tmp https://secdl.unibe.ch/FortiClientVPNSetup-Linux-amd64-current.deb
sudo apt-get remove forticlient --yes
sudo apt-get install /tmp/FortiClientVPNSetup-Linux-amd64-current.deb --yes

To remove the old workaround, execute the following commands:

grep -v '\[keyfile\]' /etc/NetworkManager/NetworkManager.conf | sudo tee /etc/NetworkManager/NetworkManager.conf
grep -v 'unmanaged-devices=interface-name' /etc/NetworkManager/NetworkManager.conf | sudo tee /etc/NetworkManager/NetworkManager.conf
sudo systemctl restart NetworkManager.service
