(Get the code!)
Interestingly, my first glance at the code of the Cisco VPN client for Linux seems to indicate that it would always default at using a MTU of 1300, since it needs to account for the worst case scenario of IP, UDP, and ESP headers that take part of the encapsulation, plus whatever else may be introduced by the added encapsulation that could come from a PPPoE connection. Not sure if it's doing the same thing for Windows or actively testing for a usable MTU value.
