Description

When you have a FQDN in an alias ans the FQDN does not resolve, the alias table creation will not happen and any other aliases that use the alias will be truncated or fail.

The root cause can be user error, but there's nothing in the system log or the firewall rebuild monitoring that indicates the failure.

This can cause a unexpected hole in the firewall, even though everything looks like it worked in the GUI.
