Uni-directional routing issues

It is important to understand that any TCP packet that is routed over a network requires bi-directional support. This means that even though I may have a route on my router to your network, if you don’t have a route back to me, the transmission of packets will fail. TCP uses acknowledgments to confirm the packet has been received, and if the acknowledgment cannot be routed back to the source the traffic will not continue to flow.
