The new username/password combination should be remembered and the password should be
composed in a way which makes it difficult to guess. The next step is to return the CLI to the
default top level of object categories.

Setting the Date and Time
Many CorePlus functions rely on an accurate date and time, so it is important that this is set
correctly using the
time command. A typical usage might be:
Device:/> time -set 2008-06-24 14:43:00
Notice that the date is entered in yyyy-mm-dd format and the time is stated in 24 hour hh:mm:ss
format.
Ethernet Interfaces
The connection of external networks to the Clavister Security Gateway is via the various Ethernet
interfaces which are provided by the hardware platform. On first-time startup, CorePlus scans for
these interfaces and determines which are available and allocates their names. The first interface
detected in the scan always becomes the initial default management interface and this cannot
be changed beforehand.
All CorePlus interfaces are logically equal for CorePlus and although their physical capabilities
may be different, any interface can perform any logical function. With the SG4500 Series, the
ge1
interface is the default management interface. The other interfaces can be used as desired. For
the sake of example, it is assumed here that the
ge2 interface will be used for connection to the
public Internet and the ge3 interface will be used for connection to a protected, local network.
Setting Up Internet Access
Next, we shall look at how to set up public Internet access with the CLI. The setup wizard
described previously, provides the following four options:
A. Static - manual configuration.
B. DHCP - automatic configuration.
C. PPPoE setup.
D. PPTP setup.
The individual manual steps to configure these connection alternatives with the CLI are
discussed next.
A. Static - manual configuration
We first must set or create a number of IP address objects. It's assumed here that the interface
used for Internet connection is
ge2 , the ISP gateway IP address is 10.5.4.1 , the IP address for the
connecting interface will be 10.5.4.35 and the network to which they belong is 10.5.4.0/24 .
Note: Private IP addresses are used for example only
