PRTG Cluster Single External IP



Hey everyone, I am currently looking into clustering and from what I have been reading from the documentation is that both of the PRTG cluster nodes have to have an external IP so that the remote probes can simultaneously connect to each cluster node? (Correct me if I am wrong in this assumption!).

Probably going to ask a dumb question, but is it possible to have both PRTG clusters behind a single external IP which is front-ended by a Load Balancer? That way, the Load Balancer can redirect the traffic to the primary node and in the event of a failure, the Load Balancer will then redirect traffic to the failover node.

This for me provides a benefit in that I wouldn't have to change 15+ Firewalls to allow the PRTG remote probe to communicate with both nodes.

Hello there,

I am afraid that it's not possible. You may check the following KB which explained about this: https://kb.paessler.com/en/topic/34123-prtgs-web-interface-behind-loadbalancer
