It's hard to tell based on no data. Anything from here would be an assumption and hear-say, since you're debugging a black box and trying to infer inner workings based on external observations. You _need_ to collect more data and observe the data at the source and destination devices, and probably in transit if you're tunnelling/fragmenting.

Thanks i will. However, the doubt is that what does introducing a 16 byte data into the steam does that causes the session to time out. I added instrumentation to push some dummy data so that instead of 16 bytes, we push 1 MB of data. In that case i saw no issues. Any idea if there is a firewall setting that could be coming into play here?

Follow the TCP stream - which side times out the link, and for what sequences of data do you get ACKs for?

Hi,
I am using a proprietary protocol and sending a bunch of bytes to a Draytek router at an enterprise site. When i send the data in TCP batches of 1 MB i see no problem. However, when i first send 16 bytes followed by 1 MB of data, and then repeat this till the entire data has beeen sent out. During this process I see that my TCP session times out. Unable to understand why this could be happening? How can sending 16 bytes of data followed by 1MB of data affect the transfer.
Thanks !
