CARP needed, limited IPs available
What I need: failover between my two pfsense boxes on 5 virtual IPs …CARP is the answer of course.
My problem: I have only 5 public IPs that I need CARPED, and thus don't have an IP for the interface.
Trolling this forum would lead me to believe this would be the proper way to start:
1.) Set my interface addresses on my two pfsense boxes to something like 10.99.99.1 and 10.99.99.2
2.) Add 5 CARP VIPs of 10.99.99.3-7.
...after this I get confused ...let's say my public IP range is 192.168.99.1-5
...it would seem that I need some sort of trickery with either static routing, "other" VIPs, and/or NATs that are different between the two boxes ...
...where to go from here?
Oh, and based on the VIP page, I do need (unfortunately) to support the FTP Helper …I bet that screws it up?

What you need, of course, is OpenBSD's CARPDEV. Unfortunately, it is still in the rough stages of being ported to FreeBSD. I think your easiest options would be: a) get a /28 instead of a /29 b) Use port-forwarding to consolidate your public services to 3 IPs instead of 5.
Thanks dotdash, in my trolling I ultimately decided you had given the answer to me …I'm upping to /28 ideally ...it's a pain with my ISP ...I actually use a lot of port forwarding to get it down to the 5 ...i could get it to 3 maybe, but that's really pushing it ...but any way, thanks again ...and looking forward to CARPDEV someday.
