3 Introduction copyright

4 Requirements You have an CenturyLink Cloud account. (The Free CenturyLink Cloud trial of VNS3 is located in your Blueprints Library) You agree to the VNS3 Terms and Conditions Ability to configure a client (whether desktop based or cloud based) to use OpenVPN client software. You have a compliant IPsec firewall/router networking device: Preferred Most models from Cisco Systems*, Juniper, Watchguard, Dell SONICWALL, Netgear, Fortinet, Barracuda Networks, Check Point*, Zyxel USA, McAfee Retail, Citrix Systems, Hewlett Packard, D-Link, WatchGuard, Palo Alto Networks, OpenSwan, pfsense, and Vyatta. Best Effort Any IPsec device that supports: IKE1 or IKE2, AES256 or AES128 or 3DES, SHA1 or MD5. *Known Exclusions Checkpoint R65+ requires native IPSec connections as Checkpoint does not conform to NAT-Traversal Standards and Cisco ASA 8.4(2)-8.4(4) bugs prevent a stable connection from being maintained. copyright

5 Getting Help with VNS3 This guide covers a very generic VNS3 setup in an CenturyLink Cloud cloud computing facility. If you are interested in more custom use cases and would like Cohesive to advise and help setup the topology contact [email protected] for services pricing. Please review the VNS3 Support Plans and Contacts before sending support inquiries. copyright

6 Firewall Considerations VNS3 Controller instances use the following TCP and UDP ports. UDP port 1194 For client VPN connections; must be accessible from all servers that will join VNS3 topology as clients. UDP * For tunnels between Controller peers; must be accessible from all peers in a given topology. TCP port 8000 HTTPS admin interface; must be accessible from hosts where you will want to obtain runtime status or configure peering, also needs to be open to and from the Controllers at least for the peering process, and needs to be accessible when downloading credentials for installation on overlay network clients. UDP port 500 UDP port 500 is used the phase 1 or IKE (Internet Key Exchange) component of an IPsec VPN connection. UDP port 4500 or Protocol 50 (ESP) Protocol 50 is used for phase 2 or ESP (Encapsulated Security Payload) component of an IPsec VPN connection only when negotiating with native IPsec. UDP port 4500 is used for the phase 2 or ESP (Encapsulated Security Payload) component of an IPsec VPN connection when using NAT-Traversal Encapsulation. *VNS3:vpn and VNS3:net Lite Edition will not require UDP ports access as it is not licensed for Controller Peering. ** Some public cloud providers require IPsec connections to use NAT-Traversal encapsulation on UDP port 4500 copyright

7 Remote Support Note that TCP 22 (ssh) is not required for normal operations. Each VNS3 Controller is running a restricted SSH daemon, with access limited only to Cohesive for debugging purposes controlled by the user via the Remote Support toggle and key exchange generation. In the event Cohesive needs to observe runtime state of a VNS3 Controller in response to a tech support request, we will ask you to open Security Group access to SSH from our support IP range and Enable Remote Support via the Web UI. Cohesive will send you an encrypted passphrase to generate a private key used by Cohesive Support staff to access your Controller. Access to the restricted SSH daemon is completely controlled by the user. Once the support ticket has been closed you can disable remote support access and invalidate the access key. copyright

8 Sizing Considerations Image Size and Architecture VNS3 Controller Images are available as 64bit images to allow the greatest flexibility for your use-case. We recommend Controller instances be launched with at least 1GB of RAM. Smaller sizes are supported but the performance will depend on the use-case. Clientpack Key Size VNS3 Controllers currently generate 1024 bit keys for connecting the clients to the overlay network via the clientpacks. Smaller or larger encryption keys can be provided upon request (from 64 bit to 2048 bit). Future releases of VNS3 will provide the user control over key size and cipher during initialization and configuration. copyright

10 Create VLAN Create a Network VLAN you want the Cohesive Networks VNS3 virtual appliance to reside on. Creating a new VLAN follows best practices so users can secure the private VIPs with firewalls. Select Networks under the Network tab of the Control Portal Dropdown menu. Click on + add network on the resulting page. A VLAN will be created for you. copyright

11 VLAN Information The resulting page will list the VLAN details as well as a list of available IP addresses. This information will be used in the Partner Template Import Request on the following page. copyright

12 Request VNS3 Partner Template Deployment VNS3 Templates are provided to CenturyLink Cloud customers via support requests. This allows Cohesive Networks to ensure the functionality of the VNS3 appliance for all users. To have the CenturyLink Cloud support team deploy the VNS3 Template in your account open a service task request ticket via to [email protected] with the following details (note the values highlighted in blue that will need to be modified per your account/vlan details): SUBJECT: Custom Image Import Request for Ecosystem Partner Template CLC Support Team, Please open a Service Task to implement a CohesiveFT Partner Template in accordance with this CenturyLink Policy ( articles/ ) and the following requirements below. Please import the Ecosystem Partner Template image file referenced below to my CenturyLink Cloud Account: - Import CenturyLink Ecosystem Partner Source Image: Cohesive Networks VNS3 virtual appliance - My CenturyLink Cloud Account Alias: #### - Data Center to import image to: ### - Server Name to import image as: ########## - VLAN in the account to add the Server to: ######## Additional Information to add Partner Template to Network: - Interface=eth0 - VLAN_free_IP=#.#.#.# - VLAN_net_mask=#.#.#.# - VLAN_gateway=#.#.#.# - DNS_servers=#.#.#.# Please let me know if you have any questions or issues. Kindly send me a reply once the work has been completed. Thank you very much, Your_Name_Here copyright

13 CenturyLink Configuration: Public IP Access Once your VNS3 image has been built, go to the Dashboard. Locate the server name you just built and select that server. Then click on the add public IP button. Click custom Port, to add the following required inbound hypervisor firewall access rules: TCP port 8000 UDP port 1194 UDP UDP port 500, and possibly UDP port 4500 When finished, you will find the Public IP is now listed on the on the server page. copyright

14 VNS3 Controller Log in Login to the VNS3 Web UI - IP>:8000 Default username: vnscubed. Default password: vnscubed Reset your passwords: Reset the Web UI Password - Even though the instance id is unlikely to be guessed, please change it for security purposes. NOTE: Your VNS3 Controller answers to API calls on the same port 8000 as the web interface runs on. Ideally make a separate password for the API usage against the Controller. Reset the API Password - Even though the instance id is unlikely to be guessed, please change it for security purposes, again making it a different password than the web interface is probably best. NOTE: Cohesive does not have any key access or remote access to your VNS3 Controllers unless provided by you. If you forget these passwords we cannot recover them for you. copyright
