[Openswan Users] Problems with xL2tp/ppp with openswan on vista

Hi guys,

to touch on this subject again also.
My user informs me he is usually disconnected during a large file 
transmission or when he's using most of the pipe for something.
I have heard the issues of MTU problems and originally set my MTU to 
1200 to compensate for any problems with that but his connection was 
completely unstable and had the most problems with a low MTU
I had recently set the MTU to 1400 and he says his connection is more 
stable but he's still having problems.

i thought the results of that was a bit backwards but i'm not that much 
of an expert in the field so someone can tell me otherwise.
Are there any other issues besides the vista rekeying problem maybe?
