Digi AnywhereUSB User Manual page 33

Appendix C:
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: 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 may add the address of the firewall into the Discovery List. Note that
AnywhereUSBs behind firewalls, as displayed in the discovery window, show the IP address of
their private network.
