ISP and this is referred to in the setup wizard as the
WAN
interface. In this guide, it is assumed
that the physical G2 interface of the E20 is used for Internet connection, although any other
unused interface could be used instead.
Direct Connection to the Management Interface
Connection to the management interface from the workstation can be done directly without a
switch. This could be done using a crossover cable. However, all the RJ45 interfaces on the E20
support
Automatic MDI-X
and a crossover cable is not necessary.
Workstation Ethernet Interface Setup
The only requirement for the Ethernet interface used for connection on the management
workstation is that DHCP is enabled. cOS Core automatically enables a DHCP server on the
security gateway's GS interfaces (numbered 1 to 4) and this allocates the required IP addresses
to the management computer using DHCP.
If the management computer is configured manually, the following settings should be used:
•
IP address:
192.168.1.30
•
Subnet mask:
255.255.255.0
•
Default gateway:
192.168.1.1
Tip: Using another workstation interface IP address
The IPv4 address assigned to the management workstation's Ethernet interface, could
be any address from the
192.168.1.0/24
network. However, the IP chosen must be
different from
192.168.1.1
which is used by cOS Core's default management interface.
