How to reset network settings on Linux?

In case you are experiencing issues with your NordLayer connection, resetting your network settings is a viable option to resolve them. A full re-boot of your Linux device should always work, but there also are more granular ways.

Reset network

In most cases, Internet connection is made via Network Manager:

sudo systemctl restart NetworkManager

Temporarily deactivate Firewall

For debugging issues, it can be helpful to deactivate the Firewall temporarily to see if that changes anything. To list Firewall rules:

sudo nft -s list ruleset      # list rules
sudo ufw status               # Ubuntu

The Firewall can be cleared until the next reboot:

sudo nft flush ruleset # clear all rules

Please note that these changes will be temporary and reverted after device reboot.
