I created a brand new vip which is quite simple....

loopback, ip alias, x.y.z.12/32

on the same subnet I am able to ping everything x.y.z.1 (DG), x.y.z.45, etc.

I am unable to ping the OPNSense VIP addresses.

From various devices I can ping the gateway. 192.168.1.1/24
I can ping from the gateway to the various devices. 192.168.1.45, 192.168.1.13, 192.168.1.15
I can ping from the gateway to the VIP 192.168.1.53, and 192.168.1.12

I cannot ping from 192.168.1.13, 15, and 45 the VIP's 192.168.1.12, or 53...

I have made no FW rule changes. what gives?

Would anyone help troubleshooting this?

I have disabled the firewalls and still unable to ping the loopback.

Check the ARP tables of your devices.
Follow the ARP packets with tcpdump and find out on which device they stop or don't arrive.
