Blocked ports Print

  • 1

For security reasons we block some network traffic to protect our customers and our network.
Exceptions can be made. If you believe you need any of ports below openned for your virtual server - feel free to open a support ticket.

On our border routers reasons we block:
  • UDP port 17 (DDoS amplifier)
  • UDP port 19 (DDoS amplifier)
  • UDP port 1900 (DDoS amplifier)
For TOR running virtual servers we block:
  • TCP port 25 (SPAM protection)
All other protocols, ports and types of traffic are allowed without any limitations.
