I have an IPv4 packet, 3523 byte of information Data a MTU (maximum transmission unit) of 516 (496 byte + 20 byte IP header), also an TCP header with 20 byte.
How does this result is created from the above information? I always come out at 51 byte Information data for the last package.
3523-(496*7) = 51
Maybe someone can shed some light on this.
