Lycan,
Thanks for the informative post. Semantics aside my objective is to have to be able to put a machine in the DMZ and have it isolated from the LAN. This is what I wanted to request as an enhancement request. Maybe the posters here don't have experience with the concept of an "enhancement request" and understood my postings as demands for changes to the product. It is exactly as it sounds. Enhancement Request. What customers don't want to hear from customer support is reasons for not accepting a reasonable request for changes. What Dlink does with the request is another story. I think little was being done in this thread to really address the customers feedback.
Can we all at least agree that the documentation on this product does not mention the limitations and LAN access risks of the Dlink or Ubicom implementation? I don't think it's unreasonable to point out and issue that can be corrected and will improve future customer service inquiries. What I have gotten here is a defensive reaction to pointing out an area of improvement. Taking this tack on issues is not going to build a better customer experience over time.
The response I should have gotten with my inquiry about opening an enhancement request as a customer is "Please do open an enhancement if you feel the product is lacking. Please document your request and send it to XXX. We take all enhancement requests seriously as we value our customers and their needs. All enahncement requests will be evaluated and prioritized by the product team and there are no guarantees that any requests will be implemented in the identified product". I don't think anyone here is going to disagree that that's really what you guys wanted to say
Please log an enhancement request on my behalf to have a feature added to the DIR-655 router firmware that prevents LAN access as much as technically possible given the hardware of the device by any machine placed in the DMZ. I am able to do this with openwrt and a cheap router and I would like to do this with the DLink DIR-655.
I'd also like to log an enhancement request for your documentation for consumer grade products that contain your current DMZ implementation to better detail the differences between Default port forwards and open LAN access VS what most think of when talking about DMZ which is something that is isolated. Customers would benefit from a security point of view. The omission of the LAN access by machines in the DMZ could be harmful to the average user.
