2.12 Accessing the WebUI
SecureSync's web user interface ("WebUI") is the recommended means to interact with the
unit, since it provides access to nearly all configurable settings, and to obtain comprehensive
status information without having to use the Command Line Interpreter (CLI).
You can access the Web UI either by using the automatically assigned DHCP IP address, or by
using a manually set static IP address (see "Assigning a Static IP Address" on page45):
1.
On a computer connected to the SecureSync network, start a web browser, and enter the
IPaddress shown on the SecureSync front panel.
2.
When first connecting to the Web UI, a warning about security certificates may be dis-
played:
