Health monitor SNAT

Hi,   I'd like to know if anyone has ever created a custom health check application or script that would be able to test an external system sourcing from a SNAT instead of the self IP of the F5. ...

I don't think there is a way to specify a source IP address in a default monitor. You might be able to use an external monitor which references a custom script. Using netcat, you could specify a source IP/port. For your specific scenario, I'm not sure how this would work though. The IP you select for the source of the monitor traffic must be an IP that the BIG-IP will ARP for. It will only answer ARPs for IP's it's configured for. So I think you'd need to configure the source IP as a self IP address.
