- Correct. Use a static IP assigned to a WAN interface.
- You would not configure an IP address for a site with only DHCP WAN interfaces.
- Recommended to enter an IP and a port for HUB sites but no recommendation on the port number. Port 4435 is in the KB example but you can use what you want.
- Recommended to configure a static IP and port on all HUB sites at a minimum, but you can add it to other sites.
- You can have multiple HUB's, usually datacenters or headquarters. Each would be configured with a static IP and port.
All accounts have WAN Recovery enabled by default in a MESH configuration. If you need to change your account to a HUB and SPOKE configuration please contact CATO Support or the Professional Services team.
