Hello there,
I tried to use my WAN IP as a virtual one to have a failover/HA but unfortunately as soon as I follow the steps which I found at pfSense forum it does not work.
I have one static IP from my ISP.
Therfore I use a private /30 range on each OPNsense box and share the real public IP via Virtual IP.
But the gateway shows always offline. I am also not able to ping my ISPs router via my real public IP.
Is anyone using HA with just one IP?
