So, summarizing, that RST was leaking your filter, one that was
filtering out all other RSTs sent as response on unused TCP ports:
You Your port lwip
TCP SYN on port x --> --> let me see
silence block! <-- RST
TCP SYN on port A --> --> let me see
got a response <-- <-- RST
because your filter in your port blocked x for all x != A, without
checking protocol field, just port field.
Did I get it correctly ?
Thx 4 the capture file.

PS: Did my table make it to the list in a readable form ?
