4.3. Manual Web Interface Setup
This section describes initial cOS Core configuration performed directly through the Web
Interface, without using the setup wizard. Configuration is done as a series of individual steps,
giving the administrator more direct control over the process. Even if the wizard is used, this
section can also be read as a good introduction to using the Web Interface for configuring key
aspects of cOS Core.
Ethernet Interfaces
The physical connection of external networks to the Clavister Security Gateway is through the
various Ethernet interfaces which are provided by the hardware platform. On first-time startup,
cOS Core 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 cOS Core interfaces are logically equal for cOS Core and although their physical capabilities
may be different, any interface can perform any logical function. With the E5, any of the GESW
interfaces acts as the default management interface. The other interfaces can be used as desired.
For the sake of example, it is assumed here that the G1 interface will be used for connection to a
protected network and the G2 interface will be used for connection to the public Internet.
Setting the Date and Time
Many cOS Core functions rely on an accurate date and time, so it is important that this is set
correctly. To do this, select System > Device > Date and Time.
By pressing the Set Date and Time button, a dialog appears that allows the exact time to be set.
A Network Time Protocol (NTP) servers can optionally be configured to maintain the accuracy
of the system date and time and this will require public Internet access. Enabling this option is
strongly recommended since it ensures the accuracy of the date and time. A typical NTP setup is
shown below.
