If there is any problem with the TCP routing in a transparent proxy
setup, and as much as a single packet bypasses the redirection then you

If you are doing packet level analyzes of a transparent proxy setup, you
need to pay attention to the ethernet addresses to determine by which
path the packet arrived.
