Portforwarding not working

Product Name

Technicolor DJA0230TLS
Software Version
Firmware Version
If I try to portforward HTTP (80) for example to UDP/TCP to my PC's internal IPv4, I goto http://canyouseeme.org/ and test port 80 and it doesn't succeed.
I was doing the same thing on my old modem pre-NBN, the modem I received post-NBN is exactly the same as my old one with a new firmware version and portforwarding worked on my old modem and im doing the exact same process?
I don't have a static IP on my PC, just a custom DNS assigned (
- UPnP = Disabled
- NAT-PMP = Disabled
- DynDNS = Disabled
- DHCP = Enabled
Any help? Thanks

Re: Portforwarding not working

Having your PC set with an IP of is going to cause some problems as that is a real IP address of a DNS service, so the request might be trying to redirect itself to an external host rather than your internal network. There is a reason why certain IP address ranges (192.168.xxx.xxx,10.xxx.xxx.xxx) are reserved for private networks, it's so this sort of thing doesn't occur.
Never be afraid to back yourself when trying new things, just always make sure you have 3 escape routes if things go wrong.

It was not working without the DNS, I'm assuming there's a bug in the latest firmware or something on Telstra's end, everything worked fine on the old modem and it's exactly the same modem just with a newer firmware

Have you set your network as a private network on the PC and also turned on Network discovery?

If your using port forwarding should use a static IP address for the computer
