Virtual IPs- Pingingable?

[quirkyferret]

I'm trying to set up a a /29 as virtual IPs for my static IPs. the primary IP that I set as my Wan works, that's fine. But my Virtual IPS don't seem to work. I've tried to set them up with both port forwarding/outbound, and 1 to 1 NATs. Neither seems to work. I've allowed ICMP through, and the WAN interface responds to pings, but the VIPs do not.

Is there any other steps i need to do other then setting up the VIP and assigning it to an interface to make it routable? I'd half love to think this is any issue with my ISP/Modem not pushing them all through, but before I open a ticket with them I would like a more fullproof test or confirmation on the Opnsense side.
