Is your feature request related to a problem? Please describe.

I want to create a rule that passes all traffic not going to any of my Networks even if my prefix changes.

Currently I can add them to a network group, but everytime I add a new interface to OPNSense i need to add it to this network group. If I forget doing this then traffic could slip to this network.

Describe the solution you like

Add an automatic alias wich contains

• all networks
• all ipv4/ipv6 addresses i have assigned on any interface
• all ipv6 prefixes I received from my ISP with PPPoE

Describe alternatives you considered

• manually creating this via network groups, but this is prone to user error as mentioned above
