Yep, 192.168.15.1 Which threw me at first as my Dlink 704P was 192.168.0.1, but anyway, I was provided with a quick install guide only and it doesn't talk about the web admin in any detail.
I was given the password by my service provider (Primus) as the gateway came preconfigured.
The service provider said NAT doesn't work on them so I would have to use another DSL router and put the 1120 in a DMZ, but then I loose voice/data prioritization or QOS.
The Dlink has the NAT feature in it so it should work just like any other router ie. linksys, dlink 600/700 series etc. Some further info:
I sent the following technical support request to Dlink:
I have a DVG-1120 that will not allow inbound connections for local services on my PC. My DL-704 worked fine prior to this gateway. I have enabled NAT (default actually) and set up the global and local port assignments but nothing.
The services are working and answering if I switch over to the 704 so it is definatly something with the 1120M. The setup is very basic so this appears as though this should work yet it doesn't. I have rebooted the gateway several time and even powered it off and back on again to no avail.
I have set up a permenant IP address and set up the forwarding to that IP so I know that request should be going to my PC. testing from an external source shows me that the 1120 is not answering on the ports that have been specified (FTP 21 for example). All inbound connection attempt time out. Port scans show no running services either.
There is a distinct lack of documentation on this product, the quick start guide is very basic and I have found no information with regards to the webmin options anywhere.
