Is pfsense doing any kind of tcp reassmebly/resegmentation, or header normalization? As tuexen@ already stated, the packet dump you provided is a perfectly vali= d, properly formatted minimum size ethernet frame, and the two bytes of (ether= net) padding should not interfere with any IP or TCP processing at all. Can you provide how the packet looks like after pfsense? But this appears not to be a TCP stack issue, IMHO. --=20 You are receiving this mail because: You are the assignee for the bug.=
