# This script stops a WireGuard VPN instance and namespace  with a given identifier.
# It removes the corresponding namespace, bridge connection, and virtual Ethernet (veth) interfaces.

# Usage: ./wg-netns-stop <identifier>

# Check if the script is run with sudo

# Remove the virtual Ethernet (veth) interfaces

# Remove the WireGuard interface from init namespace (auto removed, hence commented)
#ip link del wg0-${identifier}

# Remove the namespace folder
