pfSense

There are a number of pf table names (aka "system aliases") reserved for system use:

These reserved names are not available for use in the GUI.

Add the ability to define user-accessible system aliases for use in GUI areas that support user-defined aliases such as:

• Port forward, binat, and outbound NAT rules
• Regular and floating firewall rules
• Static routes
• OpenVPN networks
