TCP/IP MTU and MSS

BUCHANKAS — Sat, 26 Feb 2011 23:29:28 +0000

In my LAN, the MTU is 1500, and hosts A and b have an MSS of 1460.
By testing and analysing with Fireshark I sent a 4000-byte long TCP segment from host A to host B in my LAN, but the segment came in full (the 4k bytes came in one piece). Shouldn’t the 4k byte segments be broken into 1460-byte pieces according to the MSS?
The IP Don’t Fragment Flag was set, but how come a message this length being sent in one piece with this MTU and MSS?
