Can a Health Check be sourced from a SNAT address rather than the F5 self-ip?

Hey Kevin,

I'm afraid you cannot specify which IP address you want to use for health monitoring. It will use the non-floating self-IP address for the egress VLAN that's determined by the routing table.

I have seen examples of people using an external monitor and using netcat to define the source IP address.

I have also seen examples of people suggesting to create a virtual server made for monitoring, and then applying a SNAT pool on that virtual server. Then create a custom monitor with an alias address and port of the monitor virtual server so traffic passes through it and get SNATed. But I have never tried it myself.

I hope this gives some clarification and assistance.
