Another option is to use the table command, available in 10.1. I don't know what version you're using, but this particular use case seems to be pretty well suited for it.

 

 

But even then a rule may not be required (I'm not 100% clear on the use case here, so I could be wrong). Regarding the no-server bit, that's not an issue assuming you're in full proxy mode. The VIP will establish the handshake, and fire CLIENT_ACCPTED. As long as they don't send any data to us, we'll hold that connection open and it'll be subject to our tcp profile timeout. You may well be able to achieve this design simply with the idle timeout of 30 on a custom tcp profile and a connection limit of 1 set on the virtual server.

 

 

Please post back the results. Also, I'd love to hear more about the overall architecture if you're willing to share.
