Broken DMZ

This product does not work as advertized (even with latest firmware).
The DMZ port is supposed to support a network of computers. But traffic does not route properly from the internet to the DMZ or from DMZ to the internet. Packets do make it out of the WAN interface (snoop/sniffer confirms this) but the router sends malformed packets that ISP routers don't know how to respond to. In other words WAN traffic to and from the DMZ goes to the bit-bucket. LAN to DMZ works, but what good is that. Many fruitless calls to well meaning foreign help desk folks resulted in hours of wasted time.

Do yourself a favor - avoid this particular product.
