Every now and again, I come across some kind of connectivity issue relating to misconfigured MTUs somewhere along the connection path. This can manifest itself through any number of symptoms. A common problem I have seen is with VPN connectivity to Checkpoint; all other basic connectivity tests are successful, but the VPN still won't connect. So once you figure that the issue may be relating to MTUs, how do you go about testing that?

I have been having connectivity issues of a strange variety at home. I have called the ISP and had many discussions, and frankly, some argumants on my connectivity to the internet. The ISP, like all others, claims that it isn't their fault, and must be something with my wireless router, or other problem with my network and my setup. Myself, knowing exactly how this is all setup, I know this to be not the case. Or at least I am very reasonably sure...
