<p>The TCP connection MSS is set to 1460 bytes and also Don't
fragment flag is set. The server selects this MSS as a frame size
on its side and packet is dropped, probably. If you are using
linux router try to use this command "iptables -I FORWARD -p tcp
--tcp-flags SYN,RST SYN -j TCPMSS --clamp-mss-to-pmtu" or be
careful to set MTU on all client machines adapters correctly.<br>
