If you’re on Telstra, Optus, or TPG, CGNAT can block inbound connections, so consider a VPN for better inbound access and geo-unblocking. For speed and broad coverage, NordVPN is a solid top choice, with Surfshark offering unlimited devices, and PIA providing selective port forwarding on certain servers. You can install VPNs on a supported modem or behind a separate router. Note that VPNs don’t fix general congestion or data caps—keep that in mind as you configure, and there’s more ahead.
TLDR
- Prioritize VPNs with strong unblocking and proximity servers (e.g., NordVPN) for geo-restricted content on Telstra, Optus, and TPG networks.
- Consider PIA for port forwarding on select servers to address CGNAT inbound access issues common with CGNAT carriers.
- Use VPNs that support SmartDNS or easy device coverage (Surfshark or NordVPN) to maximize streaming and gaming access across devices.
- Deploy a second VPN-capable router or use bridge/passthrough setups to protect devices behind ISP-locked modems.
- Expect VPNs to help with throttling for streaming/gaming, but not fix congestion, caps, or unrelated line quality problems.
The CGNAT Problem on Australian Home Internet
CGNAT affects Telstra, Optus, and TPG differently, so you’ll want to confirm whether your plan uses CGNAT or provides an opt-out.
On NBN-fixed plans, Telstra and Optus often offer CGNAT-free options or easier port-forwarding access than their mobile services.
Meanwhile, TPG’s 5G Home Broadband and some NBN products are more likely to depend on CGNAT.
Additionally, the lack of a dedicated Ring app for watchOS means notifications are primarily relayed through your iPhone, which can influence how reliably alerts are received on your Apple Watch.
If you rely on inbound connections, plan for potential workarounds like VPNs with port forwarding or requesting a static IP where available.
Telstra, Optus and TPG Compared
Telstra generally offers a more straightforward home internet experience when it comes to inbound connections, since it states it does not use CGNAT on standard NBN-fixed services. Telstra remains the strongest fit for non-CGNAT plans; Optus and TPG show CGNAT usage variability.
| Telstra | Optus | TPG | |
|---|---|---|---|
| CGNAT likely | Possible | Yes | |
| Public IP options | Limited | Limited | |
| Inbound compatibility | High | Moderate | Low |
