I have a question as well.

Those ports 35000-65000 cover a large range.

For example, DROPBOX (www.dropbox.com), a new and very popular service as well as MOZY (www.mozy.com) which is an online system backup provider use some ports in that range for their tunnel as do a lot of other services.

When Voipo tech support was looking at my system trying to resolve some issues we removed the ports used by MOZY and DROPBOX from my Fios router. Needless to say I can't use those services at present and I am wary about reinstalling them.

Does VOIPO really need that wide range of ports or ALL the ports in that range?
