Dynamic DNS (Domain Name Service) is a method of keeping a static domain/host name linked to a dynamically assigned IP address allowing your server to be more easily accessible from various locations on the Internet.
Powered by Dynamic Domain Name System (DDNS), you can now access your Cyberoam server by the domain name, not the dynamic IP address. DDNS will tie a domain name (e.g. mycyberoam.com, or elitecore.cyberoam.com) to your dynamic IP address.
Register hostname with DDNS service provider
Select System Æ Dynamic DNS Configuration Æ Create Account to open configuration page
Screen – Register Hostname with DDNS
Screen Elements Description Host Name Detail
Hostname Specify hostname you want to use on DDNS server i.e. domain name that you registered with your DDNS service provider Specify description
Description Specify description Service Provider’s details
Service name Select Service provider with whom you have registered your hostname.
Login Name and Password
Specify your DDNS account’s login name and password
IP address Select WAN Interface if Cyberoam WAN interface is assigned Public IP address. IP address of the selected interface will be binded with the specified host name.
Select NATed Public IP if Cyberoam WAN interface is assigned private IP address and is behind NAT box.
IP Update Checking Interval
Enter the time interval after which DDNS server should check and update the IP address of your server if changed.
For example if time interval is set to 10 minutes, after every 10 minutes, DDNS server will check for any changes in your server IP address
Create button Click Create to save the configuration Table – Register hostname with DDNS
Testing your Dynamic DNS configuration
You can test your Dynamic DNS by:
• Access your Cyberoam server using the host name you have registered with DDNS service provider - If you are able to access Cyberoam then your configuration is correct and DDNS is working properly.
• Ping your host - If you get the IP address of your external interface then your configuration is correct and DDNS is working properly.
Manage Account
Check the IP address updation status from the Manage Account page. It also displays the reason incase updation was not successful.

PPPoE
PPPoE Client is a network protocol that uses Point to Point Protocol over Ethernet to connect with a remote site using various Remote Access Service products. This protocol is typically founding broadband network of service provider. The ISP may then allow you to obtain an IP address automatically or give you a specific IP address.
PPPoE Access Concentrator is a router that acts as a server in a Point-to-Point Protocol over Ethernet (PPPoE) session and is used to:
• For Ethernet LANs, to assign IP addresses to workstations, e.g. Multi-apartment buildings, Offices, to provide user authentication and accounting
• Schools and universities, computer classes
• Connections to Wireless ISPs
• Connections to xDSL providers
Access Concentrators (AC) also known as PPPoE Termination units, answer the PPPoE request coming from a client site PPPoE application for PPP negotiation and authentication.
When using Cyberoam as a PPPoE client, computers on LAN are transparent to WAN side PPPoE link.
This alleviates Administrator from having to manage the PPPoE clients on the individual computers.
To configure PPPoE Interface
Before configuring the Interface for PPPoE:
1. Run Wizard from Web Admin Console
2. In the Network Configuration, for the WAN port:
Enable option ‘Obtain an IP from PPPoE’
Under PPPoE Details, specify PPPoE username and password 3. Click Finish to exit from Wizard
4. To confirm log on to Web Admin Console, go to System Æ Configure Network Æ View Interface Details. PPPoE Interface will be defined under WAN zone.
Note:
• A new dynamic IP address will be leased to the PPPoE Interface, each time a new PPP session is establish with Access Concentrator
• IP address in Firewall rules will automatically change when the new IP address is leased
• If multiple gateways are defined then IP address in the failover condition will automatically change when the new IP address is leased
• As IP address to PPPoE interface is assigned dynamically:
a) Network Configuration from Telnet Console will not display the PPPoE interface configuration b) You will not be able to change the IP address of the PPPoE interface from Telnet Console using
Network Configuration
Select System Æ Configure Network Æ View Interface Details and click PPPoE Interface
Screen – PPPoE configuration
Screen Elements Description PPPoE Configuration
Interface Displays the Port which configured as PPPoE Interface from Wizard
User and Password
Specify username and password. Username and password should be same as specified in the Network Configuration using Wizard
Access Concentrator Name
Specify Access Concentrator name (PPPoE server).
Cyberoam will initiate sessions with the specified Access Concentrator only. In most of the cases, you can leave this field blank. Use it only if you know that there are multiple Access Concentrators.
Service name Specify Service Name.
Cyberoam will initiate only those sessions with Access Concentrator, which can provide the specified service. In most of the cases, you can leave this field blank. Use it only if you need a specific service.
LCP Interval Specify LCP interval in seconds. Default is 20 seconds. Every 20 seconds LCP echo request is send to check whether the link is alive or not.
LCP Failure Specify Failure. Default is 3 attempts. Cyberoam will wait for the LCP echo request response for the LCP interval defined after every attempt. Cyberoam declares PPPoE link as closed if it does not receive response after defined attempts.

Establish PPPoE session
1. Select System Æ Configure Network Æ View Interface Details and click PPPoE Interface through which you want to establish connection
2. Click Reconnect. It establishes 128bit tunnel with Access Concentrator. Cyberoam will automatically detect the presence of PPPoE server on the WAN interface.
Remove PPPoE Interface configuration 1. Run Wizard from Web Admin Console
2. In the Network Configuration, for the WAN port:
3. Enable option ‘Use Static IP’
4. Click Finish to exit from Wizard
5. To confirm log on to Web Admin Console, go to System Æ Configure Network Æ View Interface Details and check under WAN zone
