Describe the bug

I have a firewall group called CommonDNS that enforces my pihole DNS. It includes the LAN, and VLAN's MGMT, USER, and IOT. I have a GUEST VLAN that is not pi-hole enforced to ensure the privacy of my guests, and GUEST just uses quad9.

The CommonDNS is enforced by a RDR rule that redirects any port 53 traffic that isn't sent to my pihole to get redirected to my pihole, operating on the CommonDNS group. However, when CommonDNS is selected, even GUEST network is caught by the redirect rule. Selecting USER as the only interface to get RDR'd also results in GUEST being RDR'd.

My network is set up so that LAN is on its own line, and VLAN's on their own dedicated trunk from my switch to igb2. igb0 is WAN, igb1 is LAN, and ign3 is unused for the time being.

To Reproduce

Steps to reproduce the behavior:

1. Create RDR rule
2. Create multiple VLAN interfaces
3. Create RDR rule and only select one interface
4. View logs and observe that all VLAN interfaces are now being redirected, rather than just what was selected

Expected behavior

Only redirect traffic for selected interfaces
