With respect to my previous mail, what i ment to say was DF should be set to 0, i.e i need to enable fragmentation. Please ignore the previous error.

Have you tried turning off path MTU discovery using sysctl ("net.inet.tcp.path_mtu_discovery")? The Don't Fragment bit is set because path MTU discovery is enabled by default.


You can set sysctl variables temporarily from the command line (using <x-man-page://8/sysctl>) and permanently by adding lines to "/etc/sysctl.conf".

$ cat /etc/sysctl.conf
net.inet.tcp.path_mtu_discovery=0
