Query: no support

I purchased this item. Works fine as a firewall router. But VPN features do not work. All email and web contact to manufacturer is blocked. The only way to get a fully functioning unit with technical support for setup is to buy a 1 year service contract for $179. Amazon should include a footnote to the item description on their site that technical support for this unit is only available at extra cost.
