[DeleGate-En] Re: dropping connections with traffic when using silence parameter.

Could you show me a set of the output of tcpdump and the corresponding

Each TIMEOUT has its own default value which is non-zero usually.
You must set TIMEOUT=io:0 to cancel it.

Could you tell me what kind of protocol they are talking?
