If no one has any experience or tips to offer on getting this working, can I ask if anyone at least sees this functionality as useful? Folks I've talked to here are pretty excited about the possibilities.
What we want to do in effect is set up a Layer 3 rule with no monitoring, but make sure that any connections on any port are directed to a server that's listening on that port. If nothing is listening, the connection would be dropped.
Combined with, say, source IP persistence, this would allow us to load balance services that talk on arbitrary port ranges, or our present use case, in which we want to be able to start up servers arbitrarily on the pool members and have them load balanced (or at least highly available) without having to touch the LTM.
If we can't do this today, it sounds like a ripe, low-hanging feature request for the dev team at the least! I don't know of any other vendor who can claim in-band TCP health checking...
