Use SNAT with Monitor

Hello,

 

 

I would like to know if it is possible to use the SNAT for the monitoring ?

 

 

Use @ip SNAT to make the tests of health check, not use @ip physical appearance(physics) of the interface of F5.

 

 

I cross a firewall for the monitoring Health check, and only @ip SNAT is authorized (source IP).

 

 

Thanks in advance for your answer.

 

 

Regards,

    From what I've seen, the only option would be to configure an external monitor using netcat to specify the source IP. Otherwise, you'll have to change the fw rules. I often use my boxes to telnet to pool members for testing and since that also uses the self-ip, it's a nice capability.

    As Chris said, there isn't a native method for selecting the source IP of a stock monitor. You can use an external monitor which references a shell utility that allows for selection of a source address.

     

     

    However, you can't use shared IP addresses (floating self IP's, SNAT addresses, etc) in a redundant pair as that would cause IP conflicts when each LTM unit attempts to perform the monitor checks.
