Can't monitor vti gateways

[flyshoo]

Hello Community,
I have searched for an answer to this and can't find one.  I have setup 2 routed IPSEC VPNs with VTI networks 169.254.254.4/30 and 169.254.254.8/30. I want to monitor the VTIs but monitoring these VTIs fail.  The VPN is up and I can access all the networks across the VPNs. 
I have also observed some strange behavior, I can't ping from the shell or the WebGui but when I do a tcpdump I can see icmp traffic from the other side, Palo Alto with static route monitoring.  So I know the VTI can respond to pings but the OPNSense side won't respond or send ping requests from the VTIs.

Any ideas?

My goal is to use Gateway Group with monitoring to failover between the 2 VPNs.

OPNSense - v24.7.12_4

I guess I'll assume this isn't supported yet.
