ACCESSING IPCOPPER FROM A REMOTE LOCATION
Depending on where the USC10G4 is located, when accessing the unit from a
remote location, it may be necessary to open specific UDP and TCP/IP ports on
the firewall at the USC10G4’s location, so that the management traffic from the
utility at the remote location will be allowed through and sent along the
appropriate network route to traverse the unit (for more on how the
management utility communicates with the unit, please see page 25).
The scenarios above provide guidance on selecting an IP address for accessing
the USC10G4 when the utility is not at the same location as the unit.

Scenario 1.
In this scenario, the USC10G4 is placed at the network perimeter, inline between the
internet connection and the firewall. To access the IPCopper unit remotely, the admin/user
would use the IP address of the firewall located on the other side of the unit.

Scenario 2.
In this scenario, the USC10G4 is placed almost at the network perimeter, inline between
the firewall and the LAN. To access the IPCopper unit remotely, the admin/user would use
the IP address of the network equipment located inside the LAN, on the opposite side of
IPCopper from the firewall. In this scenario, it may be necessary to open specific UDP and
TCP/IP ports on the firewall, so that management packets would be allowed through to
traverse the IPCopper unit.

Scenario 2.
In this scenario, the USC10G4 is placed inside the LAN, in between a router and a
workgroup. To access the unit, the admin/user would use the IP address of a member of
the workgroup. In this scenario it may be necessary to open specific UDP and TCP/IP ports
on the firewall, so that management packets would be allowed through to traverse the
IPCopper unit.
