Thanks Martyn,

I have come across this MTU problem before.  Will see how it goes.

I used to have a problem on NTL/Virgin with PPTP where it would
disconnect shortly after any traffic was sent over the VPN. It turned
out the MTU of my cable router was 1500 and the SDSL router in the
office used 1492 which was clashing. Changing the cable router to use
1492 sorted the problem. I don't know how common this problem is
though.
