IMPORTANT:
Cloud users should never select the External Network when creating virtual machine instances.
Do not edit the name, ID, or administrative state of the External Network that is automatically
set during CloudSystem Foundation installation.
Do not delete the External Network that is automatically created during CloudSystem Foundation
installation. (See External Network information is not listed on the CloudSystem Portal
(page 157).)
Because you create a single subnet for the External Network, you should configure one that
is large enough to accommodate future expansion.
Prerequisite
Minimum required privileges: Infrastructure administrator
Procedure 32 Creating the External Network subnet
1. Log on to the CloudSystem Portal.
a. Append/portal to the Foundation appliance URL in your browser (for example,
https://192.0.2.0/portal).
b. Enter your user name and password, and then click Sign In.
2. From the Admin tab, in the “System Panel” section, select Networks.
The Network screen opens and displays a list of configured networks.
3. Click the External Network link.
External Network details appear on the Network Overview screen.
4. On the right side of the “Subnets section, click + Create Subnet.
The Create Subnets screen opens with the Subnet tab selected.
5. Complete the Subnet tab settings.
Subnet Name—Enter a unique name for the subnet. A maximum of 255 alphanumeric
characters is allowed.
Network Address—Enter an IPv4 address in CIDR format specifying the IP address range
to use for the subnet.
IP Version—Leave the default setting at IPv4.
Gateway IP—Enter the IPv4 address of the router providing access to this subnet.
Disable Gateway—Leave this check box cleared to allow the router to access networks
inside the cloud.
6. Select the Subnet Detail tab and complete these settings:
Enable DHCP—Click the check box to clear this option, allowing the use of floating IPs
for routing traffic.
Allocation Pools—Enter the IP address ranges to make available for floating IP address
assignment on the subnet.
7. Click Create.
Details about the External Network subnet are displayed on the Network Overview screen.
Cloud users should now be able to create routers to connect the External Network subnet to Private
networks for their projects. You can verify that a router can be connected. See Creating a router
to connect Private Network instances to the External Network subnet (page 79).
