oh if it's about ICMP fragmentation needed >> F5 receive this packet >> but i didn't found resend packet with new MTU from F5.i am confused. on page 1, you mention you cannot ping virtual server with mtu 1500. if you ping virtual server, how come does bigip receive icmp unreachable/fragmentation needed??

 

 

This problem is client can't ping to virtual server with MTU 1500. it has only one problem virtual server.
