Routes and replies

In this example, there is a TCP/IP bridge from conn_4 to conn_1 and a message with message ID 0.0.1 comes inbound to conn_1.

A reply is sent back to conn_4 with message ID 0.0.2, which is stopped. Message 0.0.3 goes outbound at conn_2 and 0.0.4 goes through an additional transformation to become 0.0.5 before going outbound at conn_3.

conn_2 is also a TCP/IP bridge that sends to conn_5. conn_5 sends a reply that is received at conn_2 as 0.0.7. it left conn_5 as 0.0.6, but arrives in conn_2 as a new inbound reply 0.0.7. conn_2 does not know that 0.0.7 left conn_5 as 0.0.6. This reply is then routed back to conn_1, where it is stopped as 0.0.8.
