Configuring for Firewall Support
To access an AnywhereUSB Remote I/O Concentrator that is behind a firewall:
• Your firewall must have a well known static IP address (for example 10.52.48.37).
• The Concentrator must have a static IP address on the private subnet (for example
192.168.1.10).
• Your firewall must be configured to allow TCP/IP and UDP/IP packets to pass through port
3422.
• The firewall must be configured to send these TCP/IP and UDP/IP packets directed to the
IP Address of the Concentrator (in this example: 192.168.1.10).
• You must manually add the address of the firewall to the Connection List.
Note that you can access only one Concentrator through each firewall. For more information on how to
configure your firewall, refer to your firewall manual.
At this point the PC will attempt to connect to the Concentrator.
If you would like Concentrator Information to be displayed in the discovery window of the configuration
utility, you may add the address of the firewall into the Discovery List. Note that Concentrators behind
firewalls, as displayed in the discovery window, show the IP address of their private network.
