# This script tries to keep WireGuard connections with dynamic peers alive #

# It resolves the endpoint if it is an FQDN, and if so, will check if the #
# currently connected endpoint matches any of the resolved IP addresses. If #
# not it will reload the WireGuard configuration in the hope that wg will #
# update the kernel with the new IP address and the connection comes back up #
# again. #
