Figure 1‑1. Default Networks in vCloud Air
Default Settings for Gateway Networks
By default, vCloud Air creates a gateway network when you assign a public IP address to a virtual data
center or gateway and configures it with the following properties:
n
Named DATACENTER_NAME-DEFAULT-ROUTED
n
Connects to the gateway through the public IP address
n
Created on the 192.168.109.0 subnet
n
Has the default gateway IP address 192.168.109.1
n
Has the following networking services enabled or disabled by default:
n
Firewall: enabled; deny all traffic
n
DHCP: disabled
n
NAT: disabled
n
Static routing: disabled
n
VPN: disabled
n
Load balancing: disabled
IMPORTANT When you initially add a gateway and gateway network in vCloud Air, you will not be able to
connect to any virtual machines added to that network and those virtual machines will not be able to
connect to the Internet. By default, gateways are deployed with firewall rules configured to deny all
network traffic to and from the virtual machines on the gateway networks. Also, NAT is disabled by default
so that gateways are unable to translate the IP addresses of the incoming and outgoing traffic. You must
configure firewall and NAT rules on a gateway for the virtual machines on its gateway network to be
accessible.
See “Add a Firewall Rule,” on page 29 and “Add a NAT Rule,” on page 24 in this guide for information.
