Ron,

I've used WinProxy before. It's a solid product, but proxy servers are very
application specific, and some apps won't work with a proxy server.

ICS, which is a software based NAT router, is easier to use. Of course, getting
rid of the USB connected modem, and getting a hardware NAT router is, by far,
the best solution IMHO.

When you mention additional (HTML?) problems with security sites, your problem
starts to sound like an MTU problem to me.
