- From the Cloud Services Portal, click Manage -> External Networks.
- On the External Networks page, select the external network to be edited and click Edit at the top Action bar.
- On the Edit Network page, complete the following:
- Network Name: Enter the name of the network. Ensure that you use a unique name for each network.
- Description: Enter a brief description of the network.
- IP addresses and ranges: Add or Remove a new IP address or range. Enter a valid IPv4 address or IPv6 address and netmask. To avoid duplicate networks and issues with ACLs defined for the DNS Firewall, BloxOne Threat Defense Cloud does not allow a CIDR block that spans across a wide range of IPs. You can enter a valid netmask between /24 and /32. BloxOne Threat Defense Cloud will return an error if you enter an invalid netmask. If you must use a CIDR block outside of this range, contact Infoblox Technical Support. Click Add to add the IP address to the list. You can add multiple IP addresses by repeating the same steps. To delete an IP address from the list, select the IP address and click Remove located on the top Action bar.
- Click Save & Close to save your configuration. BloxOne Threat Defense Cloud adds the newly created network to the Networks list.
