Description

If a client is using a CARP IP for the Network's Gateway address and sends a [x0x0] packet along UDP port 5351 on the default gateway address as RFC6886 (NAT-PMP) instructs it receives no response.

Reproduction:
1) Setup DHCP Default Gateway for CARP Address e.g. 192.168.0.1
2) Send NAT-PMP query to CARP Address 192.168.0.1
3) No Response

2b) Send NAT-PMP query directly to non-CARP router address e.g. 192.168.0.2 or 3
3) Get Response

Expected Result:
PFSense would listen on the CARP vIP for NAT-PMP\PCP requests
