Bug #2406
closedNo IP alias within the subnet of a CARP IP can be deleted
0%
Description
The input validation that triggers:
$input_errors[] = gettext("This entry cannot be deleted because it is still referenced by a CARP IP with the description") . " {$vip['descr']}.";
prevents the deletion of any IP alias within the subnet of a defined CARP IP. It's intended to keep you from shooting yourself in the foot and breaking your CARP on that subnet, but it should only prohibit deleting the last IP alias within a CARP IP's subnet as it's perfectly valid to delete any additional IP aliases within that subnet.
It can be worked around by editing the IP alias VIP and changing its IP subnet or subnet mask, then deleting the IP alias, as that same input validation is not done upon editing.

The problem is not fixed. The error still appears when you try to move the IPAlias VIP.

As proposed on bug description, the error still shows up when you try to remove the last IP alias, but do not complain when you remove additional ones. Are you getting it when trying to remove additional ones? If yes, please, post the <virtualip> section of your config.xml here.

It is the last one. pfSense should be able to determine if the alias type is CARP or IP Alias and let you remove any (even the last one) IP Alias. How are IP Aliases referenced by CARP interfaces?
I tested again going from 2 to one IP Alias left and it was able to delete all but the last IP Alias.

This is fixed. You can't remove the last IP alias on the subnet of a CARP IP because it'll break CARP, you have to delete the CARP IP first. The only exception being when the interface IP is on the CARP IP's subnet, which is also handled correctly.

This is still a problem. I have a CARP alias. I added another virtual IP in the same network for testing. I then could not delete the VIP. I had to delete the CARP IP then the VIP, then re-add the CARP IP.
