Hi Asusmy,

I have just bought rt-n12d1 wifi router from a subang parage IT store based on the salesman's confirmation that it can replaced the dlink dir-615 router. But after trying so many times with the confirmation from TM on the pppoe username and password, it just won't connect to the internet. The modem I'm using now is a ZTE white standing straight up.

Is this the correct model for the unifi router replacement?

if so, is there a userguide that i can follow?

hope you can help guide me if this is the right model. Thanks!

Thanks andrekua2, you are right. Now the Internet is working.

However, I still have one issue with the asus router. I couldn't find the NAT loopback anywhere. Do you have if NAT loopback is built in this router? any other ways that I can go around to emulate the NAT loopback?

It basically allows you to use the external wan ip or hostname such as your ddns to access from outside of home using 3g etc or from inside my house using my wifi. Basically same app one config and good for external and internal.

The old dir615 dlink has it.

Not in my case with rt-12d1. By default it isn't there. Searching through all pages in the router still couldn't find anything that's relevant to the NAT loopback. Tried enable all at the NAT passthrough still not working.

What model is yours gkong3?

Hi Raynman,

I can ping my ddns too. However once I appended the :[port], it won't work anymore.
I suppose your Minecraft server requires a specific port too? How do you get around that?

For example, sapphirecraft.dlinkddns.com:7100 ?

I meant accessing with the port on the browser. In your case

sapphirecraft.dlinkddns.com:25565

works for you on your LAN and WAN.

But in my case

xxxxx.dlinkddns.com:84

still unable to access the page (from my LAN) which I can only access from the WAN.

Tried setting the port range the same as the local port but still doesn't work.

Only port 80 and 8080 works on the LAN which leads me back to the router page.

I wonder if the router forbid certain port ranges for NAT loopback.

my firmware version is 3.0.0.4.376_2224

Yes Raynman, you are right. the latest firmware fix the NAT loopback issue. Thanks!
