One of the things in TCP/IP communications is inefficient communication/problems caused by packet fragmentation due to MTU settings along with the PATH. There is one known problem which almost everyone hits especially over IPSEC (Outlook & Exchange) on which I had blogged previously on how to find the optimal MTU value for traffic so that the packet doesn’t get fragmented => [ HERE ]

Finding the optimal MTU is relatively easy procedure along the WAN path, however it has to deal with multiple ping requests with different sized packets manually. Now I stumbled across a utility that’ll do it much efficient MTURoute

It is a free tool and does it nicely and also does have multiple options.

Use it with caution though since it produces a lot of ICMP traffic and your ISP or Network may not like it (more details on the authors page, follow the link, here
