Limiting number of concurrent connections to a member pool based on Source IP

Hi,

 

 

I need to Limit the number of concurrent connections to a virtual server based on Source IP or source subnet, so for example a given IP or subnet can have only 5 simultaneous connections at any given time with a specific virtual server if a 6th connection comes in then I'd like to reset or simply drop the incoming SYN.

 

 

Any ideas on how to do this?

 

 

Thanks,
