--- Comment #8 from zhh0000zhh <m...@zhh0000zhh.com> --- For high performance ipv6 to ipv4 forwarding, mss is required (TCP_NODELAY ON) and in rfc879 page 2, Section 3, "The MSS can be used completely independently in each direction of data flow. The result may be quite different maximum sizes in the two directions." https://datatracker.ietf.org/doc/html/rfc879#section-3 -- You are receiving this mail because: You are the assignee for the bug.
