If your TaHoma® switch is red, it has no connection to the Internet. Please check the following ports. These ports must be enabled to connect the TaHoma® to the Internet.

The TaHoma® switch accesses the following ports via external remote peers:

• 53 (DNS, UDP+TCP)
• 80 (HTTP, TCP)
• 443 (HTTPS, TCP)
• 123 (NTP, UDP)
• 18888 (TB, UDP)

These must be externally accessible. Internally, a TB free port (usually > 10,000) is automatically searched for and used. The protocol that is used is shown in brackets. The installation interface can be found in different areas of your configuration menu depending on the router / firewall provider you use. Please refer to your user manual for details. Incoming connections or port transfers do not have to be set up, as the TaHoma® switch works exclusively as a client.
