cannot connect to local machine using dynamic dns with domain name
I have two PCs, one laptop and an ipad on my network at home using BT Home Hub 6, one of the PCs has been setup to be a DMZ machine running Linux and have configured a domain name using dynamic dns to point to it, it is running a web server, http://hakimgeorge.dyndns.org, the ports are configures as follows:
I moved house and had a new bt HH6 on the new property, in my old property I had HH5.
When I am connected locally on that hub both wireleass or wired, I cannot use the domain name to access the server, it hangs with timeout. I never had this proplem on HH5. When I connect remotely it connects with no problems on the three ports I use, 80, 443, and 8090
Is there any issue or a way to configure HH6 to allow me to connect?
