Specifications

For connection to the public Internet, another E5 Ethernet interface should be connected to an
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 E5 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 E5
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 GESW interfaces and this allocates the required IP addresses to the
workstation computer using DHCP.
If the workstation 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.
