Hello Kai,

thank you, but could you tell me, if this is under Monitor or Pool.

In the Monitor the Alias Service Port the default-Setting is "All Ports", do you mean this?

Hi kgaigl,

When you create a Pool Member, you can set it ports to "* All Services".

In this case, the Pool-Member will inherit the DST port of the VS when forwarding to it. The VS could also be set to * All Services, which would allow you to setup a VS-many-to-many-Pool port mapping.

When working with such * All Services rule sets, then you have to keep in mind that the Health-Monitor wont know which port to monitor, so you have to specify a port at the Monitor-Level.

Only if you have specified a Port at your Pool-Member, the monitor will become able to inherit the Port of the Pool-Member via the default "* All services" option.

Cheers, Kai

  Ok Thank you, but this last sentence is my Problem, I think this has worked all the time, and with new pool not
  But to be sure I set the Alias Port, otherwise I could use same Monitor for different Pools
  btw: version is 16.1.3.1

    Did you set the Port on the pool level? And does the monitor not inherit its settings? Did you double checked your configuration?
