3. Check the security settings for the Cloud Data Trunk and, if necessary, change them to the
following:
• Promiscuous mode: ACCEPT
• MAS address changes: ACCEPT
• Forged Transmits: ACCEPT
4. Retry accessing the instance.
Changing the initial gateway IP address for the External Network requires
recreating a new subnet
In the CloudSystem Portal, you can specify a Gateway IP address for the External Network
subnet. If you do not specify a value for Gateway IP, it is set to the first IP address in the subnet
address pool. However, if you attempt to modify the Gateway IP at a later time, the External
Network gateway setting is not changed and, therefore, floating IP access to instances may
not succeed if the gateway is involved in the communication path.
1. Log on to the CloudSystem Portal.
2. Delete the External Network subnet.
a. From the Admin menu in the “System Panel” section, select Networks.
b. On the Networks screen, click the External Network link.
c. On the Network Overview screen, on the right side of the “Subnets” section, click +
Delete Subnets.
d. On the Confirm Delete Subnets screen, click Delete Subnets.
e. Verify that the External Network subnet is no longer listed on the Networks screen.
3. Create a new External Network subnet, specifying new IP addresses for allocation pools.
See Creating the External Network subnet (page 77).

subnet
2. Verify that DHCP is enabled, and that the gateway IP address is not the first address in the
allocation pool for the subnet.
a. From the Admin menu in the “System Panel” section, select Networks.
b. On the Networks screen, click the External Network link.
c. On the Network Overview screen, on the right side of the “Subnets” section, click Edit
Subnet.
d. On the Update Subnet screen, select the Subnet Detail tab.
e. Examine the Enable DHCP setting and the Allocation Pools list.
3. Click the Enable DHCP check box to clear the option, and then click Update.
4. Verify that the gateway IP address is listed as the first address in the Allocation Pools list.
Associate a floating IP address to the first NIC on the instance. Do not associate more than
one floating IP to an instance.
