Hello and please sorry my english mistakes.
I installed PRTG Version 220.127.116.110 as cluster in two servers with multiples network cards. For the installation and cluster setup, always I used the IP addresses of the network cards connected to the internal network. However, when going to activated the standby (secondary) prtg I saw it used the external ip address.
How to change the ip addresses used by the cluster PRTG in order to use the internal ip address and not the ip addresses of my external network? Please, take note that using the external network means open the port 23570 to all the Internet (I can't setup a rule there to restrict the ip addresses allowed).
