Description

When attempting to create a VIP (Alias type) with an IP address that has already been defined on the interface, the system performs a check and alerts the user about the IP overlap. However, that's not the case when you define Interface IP overlapping with an existing VIP using the same address. As a consequence, dpinger service won't start.

Steps to reproduce:

1) Define VIP Alias type using the WAN interface as the parent interface with an IP address, e.g., 192.168.33.21.
2) Change the existing WAN interface IP to the address used for creating the Alias (192.168.33.21)
3) Check the gateway status for the WAN interface.

Confirmed this behavior in pfSense CE 2.7.

When attempting to add a VIP that is already used by the interface, it is fine, but assigning the interface to an address used by a VIP does not stop you.
