You should not port forward port 53. That is for ddns. You are breaking your network.
DDNS does not relate to your local dns (port 53).
DDNS does not need port forward to work. But if you want to access your web (port 80) or ssh (port 22), you need to forward those port.
Mm I’m breaking his network. Sorry for bad advice 
Thanks alzhao. No problem limbot. I have stopped forwarding on 53 on both routers so now I’m back to normal router as it was before all this. I’m very much a beginner in all this so appreciate the support.
I take it that this ddns setup on the Mango should work without any port forwarding? When i do the DDNS Test on the Remote Access page of the Mango, it tells me this router is behind NAT or you do not have a public IP address. How do i get past this? Much obliged
I realise I have not said why I want to access my Mango remotely. I want to plug in a usb drive to the Mango and be able to access it from abroad. Hope that makes sense
Can you tell me if you have a fixed line broadband?
Or what kind of Internet plan you are using?
Also some screenshot of your main router are helpful.
Yes fixed line broadband from TALKTALK in the UK. Router is Sagemcom FAST-5364.
Public ip or natted ip by your provider? You can test it on wan page of your main router.
If public no problem for port forwarding…
Public IP, and NAT says disabled
Pls send screenshot of the MT300N-V2.
Ok I see.
You need to set up port forward on your 192.168.1.1 router
External 443,
Internal 192.168.1.1 443
Sorry. Internal is 192.168.1.21
Thanks alzhao. I did try that too, but when I enter my public IP:443 on the browser it doesn’t get anywhere. I switch networks to make sure I am ‘remote’ (tether my computer to my phone’s 4G). Just to confirm, the Mango is set up as Repeater, receiving internet from my main router wirelessly.
Pls pm your ddns and I will have a check.
Dear all,
I’m experiencing the same issue. Any way you managed to solve it ?
Just open new thread.
Pls give details. Each case need to be checked by its own detail.
Hi, I’ve opened a newer thread as suggested.
