I recently had to "upgrade" from a Telstra Frontier Router to Telstra Smart Modem Gen 2 due to a hardware fault and I have discovered that the "upgrade" has broken my networking setup.
It seems that NAT Loopback is not currently supported on the Gen 2 router and I cannot reached a DDNS address that points to a device in my network from within my network.
Is there a chance that NAT Loopback can be enabled in an update?
It seems strange that a Gen 2 device takes a step backwards, especially when home automation is becoming more popular.

This NBN thing is gold!
I had 100Mbps Cable Extreme for I reckon close on 10-12 years. I have moved over today to the new all-singing, all dancing NBN. Why? Because I had to, before I got disconnected.
My speed on my old coaxial cable connection 100 - 120 Mbps. It very rarely dropped below 100Mbps. I now get sub-50Mbps on my new HFC (coaxial cable) connection. For that priviliege, I get to pay an extra $20/month.
I need to use a fax machine (I know, I know - who uses faxes, right? I do because I need to) so now I have had to go and buy a virtual fax - that's another $10/month.
I have had to go our and buy a pack of cordless phones because my modem is no where near where I need telephones - more money.
By far the biggest annoyance is that my new Telstra "Smart"Modem Gen 2 does not support NAT loopback. I use NAT loopback a lot! I have now had to set up a new DNS server to kludge together a split brain DNS.
The only Telstra modem that does not support NAT loop back is the Arcadyan version off the Gen 2 smart modem. I think the latest firmware 06.07r that has just been released adds support for NAT loop back. You can check firmware version by logging into modem and going to Advanced > Info Summary.
Unfortunately there is no way you can force the update, you have to wait till it is your modems turn to be updated. Your modem has the original version off the firmware. There was a previous update to version .05.04r that was released three months ago and I am surprised your modem has not been updated to this. There might be a problem preventing the firmware update. You could try factory resetting the modem and leaving it run overnight with factory default settings.
On my Testra Sagemcom F@st5355 modem I discovered that with custom settings it would not update and had to do factory reset before the modem downloaded any firmware updates. This was fixed in one of the firmware updates.
No you are not alone. Let us know when the firmware fix arrives ... if it ever does, or yes, bye bye Telstra
