HA Setup

Hi team 👋

I'm planning to deploy SafeLine WAF HA (Master/Slave) with Pro license on bare metal servers (no cloud load balancer).

My questions:

1. For frontend load balancing between Master and Slave nodes, is a separate dedicated server required for Nginx — or can it be installed on one of the WAF nodes?
2. Which IP should I point my DNS A-record to?
3. Is failover automatic when Master goes down, or do I need to manually switch traffic to the Slave?

Thank you
