Feature #16613
closedAllow using interface subnet macros with interfaces which only contain VIPs
100%
Description
Rules which use interface macros (e.g. OPT1 subnets) are only generated when the interface contains a primary address. If the interface does not have an address assigned but does have a VIP, the rule is omitted from the ruleset.

When attempting to add a VIP to an interface that does not have a primary IP address, a validation message appears and prevents the VIP from being added.
In my opinion, if an interface does not have a primary IP address, it would be better to remove the interface address and interface subnet (for example, OPT1 address and OPT1 subnets) and then add the VIP subnets instead.

The situation occurs when the WAN is set to DHCP and the interface loses its address (e.g. the DHCP server is unavailable to give a lease). The rule generation needs to account for this when a VIP has already been assigned (while it still had an address).
