Web19 oct. 2024 · 1. @haggai_e: No. When the TCP stream starts, one client device sends a TCP SYN packet to the other client with the default MSS set. Any part of the link between them can reduce the MSS as the SYN packet traverses the link. The other client will then reply with an ACK containing the minimum MSS across the whole link.
