I have also recently had this same problem when accessing a machine via the Internet. At the server end a new cable modem had been installed, and it could not handle large packets (>1472 bytes) - they were just dropped. Replacing the modem cured the problem (although it may just have been a configuration issue related to handling IP packet fragments). To check if you have a similar problem, use the -l nnnn parameter to the ping command to make it send a larger packet, and ping the server (e.g. "ping -l 1600 myvncserver"). If small packets work, but larger ones don't (I think the maximum permissible size is 65000 bytes) you could use traceroute to find out where the problem lies. I use a great tool called PingPlotter (www.pingplotter.com) that gives a fast, continuously updated, graphical display of traceroute information and lets me configure the packet size.
