LTM as server on server and client side

It means that I will have an outside virtual server listening on x.x.x.x:7004 on the outside interface using tcp profile for remote servers to make a connection. Once a remote server connects to this virtual server I want to keep the socket and session alive. in addition I want to have an inside virtual server listening on x.x.x.x:8004 on my inside interface that will receive a connection from one of my backend servers and if the outside virtual server client is connected on x.x.x.x:7004 and available I will direct traffic from the inside virtual server to him. In essence I am performing a multiple server function for a client to connect on both my inside and outside interface and join the two together. If the outside client disappears then I either RST the connection on the inside or send no ACKS.
