Hi @Lucinda1234 ,

5G Home Broadband uses CG-NAT. Carrier-grade NAT (Network Address Translation) is a type of network that assigns services with a private IP address, instead of a dynamic public IP address. 

This means that the following items (which depend on internal NAT) will not work on 5G Home Broadband:

• Port forwarding
• Hosting web, email or file servers internally
• Smart Home systems (e.g. accessing security camera footage remotely, home automation and printers)
• Remote Access (i.e. accessing your home computer or devices from another location)

If you need any of these items in your home setup, 5G Home Broadband won’t be the right fit for you. We can help check the NBN service in your area and help you change plan.

Regards,

@Anonymous . Why are you persisting with this CG-NAT business? Cgnat prevents access to local devices from the internet. It doesn't stop local operations. I'm sure I've mentioned this before. Are Shane and BasilDV real people or just handles used by various staff at call centre?

Hmmm. No comment from the moderator.

@Lucinda1234 . The following thread has suggestions from some users about connecting to Sagemcom.

I couldn't find whether your printer connects to just one wifi band, or can connect to either. If only one, you have to disable band steering, set each band to a different name so the printer can connect.

Disable AP isolation so wifi devices can connect to the printer. An ethernet computer should not have a problem.

Suggestion to create a guest network for your printer.

Connect your previous router as an access point connected to Sagemcom. Printer connects to old wifi.
