fix VPN blocked by Telstra

Telstra is an Australian telecom provider that offers Broadband Internet, NBN, 5G, TV, and mobile phone services.

Unfortunately, many Telstra users report that their VPN connections don’t work. If you’re one of them, here’s everything you need to know to fix this problem with this ISP.

What can I do if Telstra VPN is not working?

Connect to obfuscated VPN servers

Obfuscation mode is a technique you can use to reach websites that restrict VPN access using Deep Packet Inspection.

Also known as stealth mode, it makes your VPN traffic undetectable, disguising it as a normal HTTPS connection.

Few VPN services support obfuscated servers. And we can’t think of a better provider than NordVPN. It has more than 5,100 VPN servers in 59 countries.

NordVPN supports the OpenVPN protocol and obfuscation mode, making it the perfect candidate for helping you bypass Telstra VPN blocks.

More about NordVPN:

  • 6 simultaneous connections
  • Supports Windows, iOS, Mac, Android, Linux, and routers
  • No logs or leaks
  • 24/7 live chat support
  • 30-day money-back guarantee

Connect to a different VPN server

Telstra may be the kind of ISP that blocks known VPN IP addresses. If you’re using a free VPN, you’ll likely face this issue.

Instead, you should switch to a premium VPN service like NordVPN (buy here). It supports numerous VPN servers which you can explore to find a VPN IP address that doesn’t get blocked by Telstra.

Use a different VPN protocol

Telstra could be blocking the ports used by known VPN protocols. If you’re trying to remotely connect to the workplace using PPTP, then Telstra could be restricting access to port 1723 over TCP.

If that’s the case, you can switch to different protocols such as OpenVPN, SSTP, or WireGuard.

Set up port forwarding

An alternative to changing the VPN protocol is to redirect all network traffic from one port to another. It’s known as port forwarding or port mapping, and you can change settings at the router level.

Or, if you don’t want to go through the trouble of customizing router options, check out the best port forwarding software tools.

Change DNS settings

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.

Set the Telstra firewall mode to low (not recommended)

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.

Your connection is not secure - websites you visit can find out your details:

  • Your IP
  • Your IP Address:

Companies can sell this information, alongside your location and internet provider name, and profit from it by serving targeted ads or monitoring your data usage.

Use a VPN to protect your privacy and secure your connection.

We recommend Private Internet Access, a VPN with a no-log policy, open source code, ad blocking and much more; now 79% off.
