FIX: VPN blocked by Telstra (6 foolproof solutions)

If your VPN is using the default DNS settings provided by the ISP, it might be the reason by Telstra is blocking your VPN connection.

To fix it, change the DNS settings on your device. Most VPN clients run exclusive DNS servers to speed up your Internet connection and bypass firewalls, such as NordVPN (buy here).

Alternatively, try using the public and secure DNS servers provided by Google Public DNS, Cloudflare, or OpenDNS.

Several Telstra users have reported that setting the Telstra firewall mode to low solved their VPN connectivity issue. This settings can be found in the Admin section of the router admin panel.

However, we can’t 100% recommend this workaround because it means lowering the security of your router and exposing your home network to a wide range of web-enabled vulnerabilities, such as DDoS attacks.

A safer alternative is to find and whitelist your VPN in the Telstra modem settings.


To recap, if your VPN isn’t working on Telstra, you can fix this issue by connecting to obfuscated servers, another VPN server, or another VPN protocol.

However, you can also set up port forwarding and change your DNS settings. You can also try setting the router firewall mode to low, but we don’t recommend this for security reasons.
