Network Connections
To access the Connection Wizard, click the Network Connections icon on the side bar. The Network Connections screen will appear, listing all current connections. On the Network Connections screen, you can create, view, or modify the network connections of the USR8200 Firewall/VPN/NAS. Within this area, you can create or modify four types of network connections:
WAN Ethernet ConnectionClick WAN Ethernet to view the information for your WAN connection.
If you need to modify any of the settings for WAN connection, click Settings.
When you are finished modifying any of the settings, click Apply and then click OK. LAN Ethernet ConnectionClick LAN Ethernet to view the information for your LAN connection. If you need to modify any of the settings for your LAN connection, click Settings.
When you are finished modifying any of the settings, click Apply and then click OK.
New ConnectionClick New Connection on the main Network Connections screen if you need to create a new network connection. Along each step of the way, you will be presented with explanations of the choices at hand. In some cases, you will be required to specify networking parameters, so make sure you have your network information available. Check with your network administrator if you have any questions about your network configuration. In the New Connection window, you will need to select the type of network connection you want to create. Click Next when you have selected one. Follow the on-screen instructions and enter the appropriate information for the type of network connection that you need to create. When you are finished, the new network connection will appear under either WAN Network or LAN Network, depending on what type of network connection you created.
Creating Advanced ConnectionsThis section is intended for the advanced user and assumes intermediate computer networking proficiency. Creating a Point-to-Point Protocol over Ethernet (PPPoE) Connection Creating a Network Bridge Connection
Creating a Point-to-Point Protocol over Ethernet (PPPoE) Connection Some ISPs require the use of PPPoE to connect to their services. This is generally used for DSL connections. Contact your ISP for more information. To create a PPPoE connection, perform the following steps:
Creating a Network Bridging Connection A Network Bridge enables you to connect network segments. It offers increased flexibility by allowing a mixture of media types and by automating the difficult configurations that are normally associated with mixed media networks. The Network Bridge creates a software connection linking different types of network connections and creating a single subnet for the entire network. To create a Network Bridging connection, perform the following steps:
Creating a Virtual Private Network (VPN) ConnectionA Virtual Private Network (VPN) allows the home or SOHO user to establish a secure and cost-effective communications path over the Internet, linking a local network to a remote computer or site. Widely used VPN technologies such as IPSec and PPTP allow users to safely and securely access a company intranet from a remote location or connect to the home/SOHO network when traveling. The USR8200 Firewall/VPN/NAS's three modules, IPSec, PPTP Server, and PPTP Client, enable computers on the local network to communicate over VPN connections with remote computers without needing to run any additional VPN software. Pass-through support allows computers on the local network to establish direct VPN connections with remote servers passing through the gateways Firewall and NAT. There are four types of VPN connections you can create: Point-to-Point Tunneling Protocol, Point-to-Point Tunneling Protocol Server (PPTP Server), Layer Two Tunneling Protocol (L2TP), and Internet Protocol Security (IPSec). Layer Two Tunneling Protocol Connection
Creating a PPTP Client Connection Point-to-Point Tunneling Protocol (PPTP) is an extension of the Internet's Point-to-Point Protocol (PPP) that allows two computers to establish a Virtual Private Network (VPN) for themselves over the Internet by creating a virtual serial link. PPP encapsulates data from the Network layer (e.g.: IP, IPX) into the HDLC format, this data is encapsulated into the GRE protocol format and is sent over the public network. Your gateway can act both as a PPTP server, enabling external users (clients) to access the LAN and as a PPTP client, enabling users within the LAN to access a remote LAN. The PPP authentication protocols include: PAP, CHAP, MS-CHAP, and MS-CHAPv2. The PPP encryption protocols include: MPPE40, MPPE128, and MPPE-STATELESS. To create a PPTP client connection, perform the following steps:
Creating a PPTP Server Connection To create a PPTP server connection, perform the following steps:
Note: Changing any of the user parameters will prompt the connection associated with the user to terminate. For changes to take effect, you should activate the connection manually after modifying user parameters.
Layer Two Tunneling Protocol Connection To create a Layer Two Tunneling Protocol connection, perform the following steps:
IPSec is a series of guidelines for the protection of Internet Protocol (IP) communications. It specifies procedures for securing private information transmitted over public networks. The IPSec protocols include:
Services supported by the IPSec protocols (AH, ESP) include confidentiality (encryption), authenticity (proof of sender), integrity (detection of data tampering), and replay protection (defense against unauthorised resending of data). IPSec also specifies methodologies for key management. Internet Key Exchange (IKE), the IPSec key management protocol, defines a series of steps to establish keys for encrypting and decrypting information; it defines a common language on which communications between two parties is based. Developed by the Internet Engineering Task Force (IETF), IPSec and IKE together standardise the way data protection is performed, thus making it possible for security systems developed by different vendors to interoperate. To create an IPSec client connection, perform the following steps:
Internet ConnectionIf you need to setup your connection to the Internet, click Internet Connection. Select your Internet Connection type and click Next. Enter the appropriate information for your Internet Connection and follow the on-screen instructions. When you are finished, you should have a secure connection to the Internet.
