Chapter 4 4. 7 Configure VPN Configure the Network with Omada SDN Controller Overview VPN (Virtual Private Network) gives remote LANs or users secure access to LAN resources over a public network such as the internet. Virtual indicates the VPN connection is based on the logical end-to-end connection instead of the physical end-to-end connection. Private indicates users can establish the VPN connection according to their requirements and only specific users are allowed to use the VPN connection. The core of VPN connection is to realize tunnel communication, which fulfills the task of data encapsulation, data transmission and data decompression via the tunneling protocol. The gateway supports common tunneling protocols that a VPN uses to keep the data secure: ■■ IPsec IPsec (IP Security) can provide security services such as data confidentiality, data integrity and data authentication at the IP layer. IPsec uses IKE (Internet Key Exchange) to handle negotiation of protocols and algorithms based on the user-specified policy, and to generate the encryption and authentication keys to be used by IPsec. IPsec can be used to protect one or more paths between a pair of hosts, between a pair of security gateways, or between a security gateway and a host. ■■ PPTP PPTP (Point-to-Point Tunneling Protocol) is a network protocol that enables the secure transfer of data from a remote client to a private enterprise server by creating a VPN across TCP/IP-based data networks. PPTP uses the username and password to validate users. ■■ L2TP L2TP (Layer 2 Tunneling Protocol) provides a way for a dialup user to make a virtual Point-to-Point Protocol (PPP) connection to an L2TP network server (LNS), which can be a security gateway. L2TP sends PPP frames through a tunnel between an L2TP access concentrator (LAC) and the LNS. Because of the lack of confidentiality inherent in the L2TP protocol, it is often implemented along with IPsec. L2TP uses the username and password to validate users. ■■ OpenVPN OpenVPN uses OpenSSL for encryption of UDP and TCP for traffic transmission. OpenVPN uses a client-server connection to provide secure communications between a server and a remote client over the internet. One of the most important steps in setting up OpenVPN is obtaining a certificate which is used for authentication. Omada SDN controller supports generating the certificate which can be downloaded as a file on your computer. With the certificate imported, the remote clients are checked out by the certificate and granted access to the LAN resources. 114

4. 7 Configure VPN

Overview

VPN (Virtual Private Network) gives remote LANs or users secure access to LAN resources over a public

network such as the internet. Virtual indicates the VPN connection is based on the logical end-to-end

connection instead of the physical end-to-end connection. Private indicates users can establish the

VPN connection according to their requirements and only specific users are allowed to use the VPN

connection.

The core of VPN connection is to realize tunnel communication, which fulfills the task of data

encapsulation, data transmission and data decompression via the tunneling protocol. The gateway

supports common tunneling protocols that a VPN uses to keep the data secure:

■

IPsec

IPsec (IP Security) can provide security services such as data confidentiality, data integrity and data

authentication at the IP layer. IPsec uses IKE (Internet Key Exchange) to handle negotiation of protocols

and algorithms based on the user-specified policy, and to generate the encryption and authentication

keys to be used by IPsec. IPsec can be used to protect one or more paths between a pair of hosts,

between a pair of security gateways, or between a security gateway and a host.

■

PPTP

PPTP (Point-to-Point Tunneling Protocol) is a network protocol that enables the secure transfer of

data from a remote client to a private enterprise server by creating a VPN across TCP/IP-based data

networks. PPTP uses the username and password to validate users.

■

L2TP

L2TP (Layer 2 Tunneling Protocol) provides a way for a dialup user to make a virtual Point-to-Point

Protocol (PPP) connection to an L2TP network server (LNS), which can be a security gateway. L2TP

sends PPP frames through a tunnel between an L2TP access concentrator (LAC) and the LNS. Because

of the lack of confidentiality inherent in the L2TP protocol, it is often implemented along with IPsec.

L2TP uses the username and password to validate users.

■

OpenVPN

OpenVPN uses OpenSSL for encryption of UDP and TCP for traffic transmission. OpenVPN uses a

client-server connection to provide secure communications between a server and a remote client over

the internet. One of the most important steps in setting up OpenVPN is obtaining a certificate which

is used for authentication. Omada SDN controller supports generating the certificate which can be

downloaded as a file on your computer. With the certificate imported, the remote clients are checked

out by the certificate and granted access to the LAN resources.
