oh yes, i forgot the DF bit.
there is a lot of how-tos and faqs about using vpn in the internet.
i am not sure, however, if there is a general solution that can be
applied to every infrastructure.

most companies are still struggling hard with getting their vpn
products fully compatible.

i cannot help with the win2k concentrator as i didn't know there is
such a thing until now. :o).

good luck anyway.

Hi,

This sounds like problems with the "Do Not Fragment" bit. You can download
small things but hang on large ones. Are you behind a firewall? Does your
firewall allow ICMP outwards? When a packet with DF set hits a device that
must fragment, that device sends an ICMP 3/4 (destination unreachable,
fragmentation required). If that ICMP doesn't get through your firewall
you get the symptoms you describe.
