It can work as a main or backup link, but standard Starlink plans sit behind carrier-grade NAT, so inbound access such as port forwarding or remote CCTV viewing often fails. A business plan with a public IP, or an outbound tunnel, can solve that.
The inbound access problem
Residential and roaming plans share public addresses, so you cannot forward ports to a device on your network. Some CCTV systems work anyway because they connect outbound to a cloud service. Others do not.
Ways to make it work
- Business plan with a public IP. Reports say a public address can be enabled on business plans, but it may change over time, and it is not the same as a fixed address. Check current terms with Starlink.
- Outbound tunnel or VPN. Services such as Cloudflare Tunnel or Tailscale avoid the need for inbound ports.
- Cloud-connected CCTV. Use a recorder that connects outbound.
Plan the installation properly
- The dish needs a clear view of the sky, so trees and buildings reduce performance.
- Connect it to a business firewall’s WAN port, not a consumer router.
- Add a 4G or 5G backup for important sites.
Quick answers
Can I get a fixed IP address on Starlink?
Reports conflict, so check the current business terms with Starlink before you design anything around a fixed address.
Is Starlink good as a backup line?
Yes, it is a useful second route for a site that cannot afford to be offline, especially alongside a 4G or 5G link.
