Hi i have the Sagemcom 5366TN Modem Set up with NBN. Recently I just wanted to set up a port forwarding for a Minecraft server with friends. When adding the port I have chosen:
Internal Host: 192.168.0.24
Internal Port: 25565
External Port: 25565
The port was listed enabled and i have applied. However, when I use port checkers from the internet it says that the port is closed. Any ideas on how to solve this?
Hey @YaTng have you had a look into our Modem Guides as of yet? These will provide you with some more information and guides on the devices setting to assist with any set up enquiries you were having.
Should you continue to have issues, I would recommend having a chat to our Messenger teams whom will be able to look into your services and advise further. Our teams are available 24/7 via the Optus App

No, what happened was that the port scanner got no response to its port scan and assumed that the port was closed.
Port scanners are useful but not foolproof. There has to be something ready, willing and able to respond to a ping in order for it to be reported as open.
For a computer (see here) you need to port forward:
If that does not work then you need to isolate the problem as much as possible.
To rule out the computer firewall you can temporarily disable it while you do your testing.
If your NBN is anything other than FTTN or FTTB then you can rule out the 5366 as the problem by bypassing it all together and temporarily connecting your computer to the NBN box directly.
