Open Internet ports that have been blocked

For your security, we block some ports by default in your Internet connection. Do you wish to open them anyway, e.g. for a program or your website? Then you’ll read here which internet ports can be opened manually in MyProximus.

Ports that you can open

These internet ports are closed for incoming traffic, but can be opened in MyProximus:

  • Port 23 (Telnet protocol)
  • Port 80 (HTTP protocol)
  • Port 443 (HTTPS protocol)

Getting started

  1. Log in to My products.
  2. Click on an Internet subscription in the Internet section.
  3. Select Technical profile in the Services box: Normal is check-marked by default.
  4. Select Basic and click the Confirm button.
  5. Switch off your modem for 5 seconds and switch it on again.

You have unblocked ports 23, 80 and 443. They are now open for incoming traffic.

Ports that can't be opened

The internet ports below are blocked for incoming and/or outgoing traffic. For security reasons, you cannot unblock them yourself.

Ports 25 and 445 (TCP protocol); ports 135, 137, 138 and 139 (UDP protocol); ports 1080, 1555, 2001, 2280, 2281, 2282, 2284, 2285, 3128, 8080, 8081, 9000 and certain ports higher than 1024.
