Configuring WAN address

[francisaugusto]

Hi,

I've seen some of the tutorials to configure CARP and HA, but one thing isn't clear to me:

On every tutorial, we need to configure private IP's for WAN. So the master gets like 10.1.0.20, the slave 10.1.0.30, and the CARP gets something like 10.1.0.1.

I have two questions:

- Where's the WAN IP assigned by the ISP configured, since the WAN interface is configured with those private IP's?
- I plan to use to VM's for the two OpnSense installs, on different machine. Is that ok to use vlan interface to connect both installs?
