Fiddler is an HTTP proxy that, among other things, allows one to pause outgoing and incoming HTTP packets, modify their contents and continue.

Is there anything similar to this working in lower layers of the OSI model? In particular, I want to be able to pause a TCP ACK packet and later let it continue through the pipeline. *nux or Windows suggestions are appreciated.

On a Cisco device, I know that enabling debugging can incur a performance hit since debugging has such a high priority on the CPU.
