IP Aliases cannot be used for routes/gateways
Added by allen landsidel over 11 years ago.
Updated about 11 years ago.
Description
Version: 2.0.3-PRERELEASE, 2.1-BETA1 (Apr 18 2013).
Short: The system will not allow a gateway to be created where the IP is within a subnet used by an IP alias -- only the main/primary IP subnet of an interface can be used.
Example:
Two pfsense firewalls. FWA and FWB. Three IPv4 subnets. 192.168.0.0/24, 192.168.1.0/24, 192.168.2.0/24. Assigned as:
FWA: 192.168.0.1 (LAN), 192.168.2.1 (LAN IP Alias)
FWB: 192.168.1.1 (LAN), 192.168.2.2 (LAN IP Alias)
Attempting to define a gateway of 192.168.2.2 in "System -> Routing -> Gateways" on FWA fails with the message that 192.168.2.2 is not within the LAN interface subnet, 192.168.0.1.
Expected Behavior:
Should "just work" with no error message. Works as expected on all normal routing hardware, as well as on standard *BSD installations via "route add ..."

Thanks. Will test as soon as it makes it into a snapshot build. Didn't seem to be in the latest one.

Was the expected result of this revision to prevent the deletion of Virtual IPs that also exist in the same subnet as one of the gateways? Why? I am working on reconfiguring one of my boxes and I would like to delete a virtual IP that is in the /29 subnet of my WAN IPs. I am making some minor topography changes to my infrastructure and would like to delete this virtual IP. I am getting this message "This entry cannot be deleted because it is still referenced by at least one Gateway." This message was part of this revision. However, I have been able to perform this procedure without issue in previous versions.
