How to clear Don't Fragment (DF) bit

You're quoting wikipedia at me for standards? Shame on you... It's worth exactly what you paid for it (For references see some amusing tales regarding new organisations who use it for references and them get found out because the info is just plain suspect).

And who said (Or implied?) anything about minimum MTU of 1500 for ethernet? 1500 is THE MTU for ethernet. Apart from obvious extensions like Jumbo frames on Gb+ networks. You know one of the BIGGEST things to go wrong with token-ring networks in the days when TR and Enet were fighting it out? Variable MTU's. Caused way too many problems. The last big issue I had with a VMS admin... Wrong MTU's... Yes, it might solve/work-around THIS issue. Yes it will more than likely raise aNOTHER issue somewhere else. Much better to fix it properly at source.

 

 

Like I said... The admin who configured the ICMP messages to be dropped probably thought he was doing something harmless too..
