Cannot Properly Configure Carp

[lau.xiong]

When I tried to configure CARP the 'legacy' way, this process no longer works, especially when creating NAT Outbounds, ie, I can no longer specify the mask, eg, "10.0.0.1/32", "127.0.0.0/8" and so on.

The submask is no longer selectable now, so I can only do these: "https://drive.google.com/open?id=1pyXZgwzL_38DX-TX_s8qswHgsAAqXqgN"

What is the most current configuration method for 18.7.x CARP configuration as this "https://wiki.opnsense.org/manual/how-tos/carp.html" is very vague and no longer seems applicable.

With this said, has anyone actually succeeded in getting HA/CARP working with the latest builds of OPNSense? (May I see some of the screenshots of same?)

Thanks!
