Aspects of the subject matter described herein relate to symmetric routing to a private network. With the composition of the invention the natural level of chylomicrons is maintained, in particular in gut associated lymphoid tissue, which ensures that most of LPS andor LTA which are released in the body can be neutralized, substantially decreasing the risk of locally occurring high levels of LPS andor LTA and thus sepsis. The wedge screw member has a non-tapered body threadingly engaging the spool member side portion, and a non-threaded, radially sloped surface area rampingly engaging the sloped shim surface area.
