Change MTU in µTorrent?

[blEnder]

I'm using µTorrent through a VPN and one of the things I've read that it is wise to change the MTU for ones torrent app to 1400 instead of the windows 'default' of 1500.

There is a setting in Azureus that allows you to change the MTU in the client itself, but I cannot find a setting in µTorrent that will do the same.

Any thoughts?

Thanks.
