DLINK DVG-1120M/PR

how did you access the webadmin interface ? I am asked for a userneme/password ?

Why? Are you going to take it apart? I have the DLINK DVG1120M and the user guide is more than sufficient.

I am using it with ATT CallVantage service over Comcast broadband.

My LinkSys router works fine with it. You DO have to power off all units then power them up IN SEQUENCE: modem,wait, Dlink, wait, Router, and computer. (I use an iMac and a couple of PCs)

If RealVNC is a VPN that would be a problem.

Do you mean webadmin for the Dlink? How did you get the IP or MAC for the Dlink?

Interesting; would like to discuss further. - RM

Found the IP to be 192.168.15.1 and the Dlink has a pretty nifty webadmin indeed! - RM

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.

Dlinks response:

Unfortunately, the current firmware version 17d in this box from AT&T has some problems with port forwarding. D-Link and AT&T are currently looking into this and hopefully another firmware in future will address this problem. Sorry for any inconvenience

No I meant the VoIP service provider and they are correct, as confirmed by Dlink, there is a firmware issue with these units that prevents NAT/IP forwarding to internal hosts. Bummer!

Hooking my VoIP gateway up to another gateway is just ridiculous. Guess I will have to wait for a fix.

That has to be b.s. or a misunderstanding...asuming you meant ISP.

Right, and I think QoS is important.

That's true, but I'm still more comfortable using the Linksys. Apparently dual NAT is not a problem and doesn't really slow things down.

You are supposed"' to be able to forward (DMZ) from the TA just as from a NAT router, but doing it is not yet clear! - RM

You mean for forwarding an IP without NAT, is that it? (Because my dvg-1120m forwards just fine, but I'm not trying to run a server behind it.)

But if you put the TA after the ROuter and tell the router to put the TA in a DMZ (whew!) that should work, but you could not get QoS to work. Yes?
