Hello, I am running a FreeBSD router with two ethernet cards. I have reduced the MTU to 800 in order to generate ICMP packet "Fragmentation needed but DF was set". I can find in log : rl1: discard oversize frame (ether type 800 flag 3 len 875 > max 814) But there is no ICMP sent. By default, is this feature disabled ? How can I see these ICMP packets generated ? Regards. Eric
