This has been an issue for a long time now. Many sites do not open as packets get dropped when encapsulation happens. It is seen more often when you have control connections getting dropped. PPP control connections is one such case. I've also noticed this more often in sites that are served out of large web farms/ CDNs which have some kind of indirection/ reverse proxy. LinkedIn is a standing example. -- Mohan Sundaram _______________________________________________ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
