PUREVPNHow to Port Forward on Aussie Broadband and bypass CGNAT in Australia

If you’re an Aussie Broadband customer trying to port forward, you may have noticed it’s not working. That’s because your traffic is being NATed by the Aussie Broadband network. This guide explains how to open ports on Aussie Broadband. 

What is Port Forwarding? 

Port forwarding is a networking approach that permits gadgets or services to enter a specific device or service within a private network. It includes directing network traffic from a particular port on a router or firewall to a corresponding port on a device in the network.

Let’s say you have a safety digital system connected to your home network. You could use port forwarding to view the digicam record from outside your private home. 

You’d configure your router to direct incoming traffic on a particular port ( like 8080) to the local IP of your camera system on the same port.

What Ports Are Blocked by Aussie Broadband? 

Aussie Broadband, like many internet providers (ISPs), may additionally block specific ports for many reasons associated with network security, client protection, and compliance with industry requirements. Here are some ports blocked by Aussie broadband:

Blocked Outbound Ports 

To reduce spam emails: Port TCP-25. 

Blocked Inbound Ports 

  • To prevent unauthorized web access, Port TCP-80 (HTTP) and Port TCP-443 (HTTPS) 
  • Port: TCP-25 
  • To avoid unauthorized remote access: Port UDP-135 (RPC)
  • To prevent exploitation from malicious users: Port UDP-137 to 139 (NetBIOS)
  • To avoid DDoS attacks: Port TCP/UDP-11211

How do I remove NAT from Aussie Broadband?

If you have a legitimate reason and want to remove NAT, call Aussie Broadband technical help support at 1300 880 905, and they can remove your service.

Opting out of NAT will result in your specific public IP address changing, except you’ve got a static IP implemented in your service. Here is how you can remove NAT from broadband if you don’t want to contact them:

  1. Use a static IPv4 address for your network.
  2. Open your Aussie broadband’s provided router and go to NAT settings.
  3. Change settings to bridge mode or Modem-only mode to disable NAT.
  4. Done! Save the settings and restart your router.

What is CGNAT?

CGNAT (Carrier-grade NAT) is a type of NAT technology used by Internet service providers. CGNAT allows ISPs to save on IP addresses by sharing a small pool of IP addresses among many customers. This helps reduce the number of IP addresses the ISP needs to divide among its customers. 

Why does Aussie Broadband perform CGNAT?

Most ISPs are performing CGNAT to continue operations even with their IPv4-based architecture. Firstly, the transition toward the IPv6 protocol is a pretty slow process, and ISPs have to use the IPv4 structure, which is expensive. 

By performing CGNAT, ISPs can assign the same IP address to many users. This reduces the number of IP addresses to be allocated. Plus, reducing the number of IP addresses needed to be acquired by ISPs.

Why is Port Forwarding an issue on Aussie Broadband?

Port forwarding is an issue because of how the Aussie Broadband network works. Port forwarding routes traffic from the internet to a specific device on your home network. This can be useful if you want to run a server or other service on your home network that needs to be accessible from the outside world. But, it can also be a security risk if not configured correctly.

Aussie Broadband performs CGNAT (Carrier-Grade Network Address Translation) on their network. This means that all customers share a single public IP address. This can cause problems with port forwarding because the traffic from the outside world is routed via CGNAT.

Some workarounds can help you port forward Aussie Broadband. But, they can be complex and may not work in all cases.

Frequently asked questions

Does Aussie broadband use CGNAT?

Yes, Aussie Broadband does use CGNAT (Carrier-Grade Network Address Translation). Your public IP address will be shared with other customers on our network. Your public IP address can change from time to time, but it will always be in the range of to

If you need a static public IP address, we offer this as an optional add-on for an additional monthly fee. Please get in touch with our support team if you want to add a static IP to your service.

Does CGNAT affect Port Forwarding?

Yes, Carrier-Grade Network Address Translation (CGNAT) can affect port forwarding. This is because CGNAT typically uses an extensive range of IP addresses, which makes it challenging to forward traffic to a specific device on the network. Additionally, CGNAT can change the source IP address of packets, which can also cause problems with port forwarding.

What ports do Aussie broadband block?

Broadband providers in Australia typically block specific ports commonly used for activities that violate copyright law. This includes port 80, which is used for HTTP traffic, and port 25, which is used for SMTP traffic. Some providers may also block port 21, which is used for FTP traffic.

How do you tell if you are behind CGNAT?

If your device is behind CGNAT, you will likely see a firewall or NAT warning when you connect to certain websites or applications. This is because the CGNAT server is translating your device’s IP address, and the website or application you’re trying to reach doesn’t recognize the translated IP address.
You may also experience slower internet speeds when behind CGNAT, as your traffic is routed through the CGNAT server.
If you suspect your device is behind CGNAT, you can contact your ISP to confirm and find out if there is anything you can do to change your IP address.
