Port Blocking at Westnet

Data moves around the internet through ports. When a port is blocked, data can't move through it. There are certain ports that aren't necessary for everyday interent use, but they are commonly used for network attacks.  Blocking these ports helps to protect our users from security threats.

 

Ports blocked by default

The following ports are blocked by default:

  • Port 25 (SMTP) incoming/outgoing - except to Westnet email servers i.e. mail.westnet.com.au
  • Port 80 (http) incoming
  • Port 135 (netBIOS) incoming
  • Port 139 (netBIOS) incoming
  • Port 443 (https) incoming
  • Port 445 (TCP/UDP) incoming

 

How to disable default port blocking

Some advanced users such as business customers or people running their own servers may need to disable the default port blocking so they can continue their day to day operations.

  1. Log in to MyAccount.
     
  2. Select your broadband service.
     
  3. Select Settings, or Manage port blocking.
     
  4. Set the toggle switch to OFF and then click Change settings to finish. If this button is not present in your MyAccount, changes will be saved automatically.
     
  5. Your changes may take up to 15 minutes to take effect.
