Network Configuration

The identification of your Across Server for other Internet users (e.g. other Across Servers and/or crossWAN load Clients) is done by means of IP addresses.

The communication or data exchange with the above-mentioned external Across Servers and crossWAN load Clients takes place via so-called ports.

In order to enable data communication with external Across Servers or Clients, firewall ports must be opened.

If a firewall is active on the clients, you need to open the ports specified in the following figure.

The following figures show the required firewall settings for some common installation scenarios. The specified ports are the default ports that are predefined by Across. These ports can be changed if necessary.
