How to clear Don't Fragment (DF) bit

sorry, i mean icmp unreachable/fragmentation needed should not be dropped, should it?

 

oh if it's about ICMP fragmentation needed >> F5 receive this packet >> but i didn't found resend packet with new MTU from F5.

 

 

Is there a reason this is important to you? PING doesn't seem to like a critical function to me, or is this actually affecting application traffic too?

 

sorry I mistook this all of time , point is not ping , ping is just show how to test this. customer use tcp normally .
