Appendix C: Configuring for Firewall
Support
To access an AnywhereUSB that is behind a firewall:
• Your firewall must have a well known static IP address, for example, 10.52.48.37.
• The AnywhereUSB must have an 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 AnywhereUSB; in this example the address would be 192.168.1.10.
• You must manually add the address of the firewall to the Connection List.
Note that you can access only one AnywhereUSB 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 AnywhereUSB.
If you would like AnywhereUSB Information to be displayed in the discovery window of the
configuration utility, you can add the address of the firewall into the Discovery List. Note that
AnywhereUSB devices behind firewalls, as displayed in the discovery window, show the IP
address of their private network.
