Connect an Ethernet cable between the RV320 and its DSL or cable modem, and connect an Ethernet cable between the ISR2900 and its cable or DSL modem. IPSec SAs terminate through deletion or by timing out. Data is transferred between IPSec peers based on the IPSec parameters and keys stored in the SA database. IKE negotiates IPSec SA parameters and sets up matching IPSec SAs in the peers. IKE authenticates IPSec peers and negotiates IKE SAs during this phase, setting up a secure channel for negotiating IPSec SAs in IKE phase 2. Traffic is deemed interesting when the IPSec security policy configured in the IPSec peers starts the IKE process. Interesting traffic initiates the IPSec process. Yet, IPSec's operation can be broken down into five main steps: Step 1. IPSec involves many component technologies and encryption methods. IPsec supports network-level peer authentication, data origin authentication, data integrity, data confidentiality (encryption), and replay protection. A secure policy for every peer must be manually maintained.,/p> Internet Protocol Security (IPSec) Internet Protocol Security (IPsec) uses cryptographic security services to protect communications over Internet Protocol (IP) networks. IKE builds on the Oakley protocol, Internet Security Association, and Key Management Protocol (ISAKMP), and uses a Diffie Hellman key exchange to set up a shared session secret, from which cryptographic keys are derived. Key Features Internet Key Exchange (IKE) Internet Key Exchange (IKE) is the protocol used to set up a security association (SA) in the IPsec protocol suite. 1 of 6 12/5/13 12:12 PMÄ¢ With this configuration, a host in Network B at the Remote Office and a host in Network A at the Main Office can communicate with each other securely over VPN. #EASYVPN RV320 SERIES#A site-to-site IPsec VPN tunnel is configured and established between the Cisco RV320 Gigabit Dual WAN VPN Router at the Remote Office and the Cisco 2900 Series ISR at the Main Office. Applicable Devices Cisco RV320 Routers Cisco 1900/2900/3900 Series Integrated Services Routers (ISA2900) Example Network Configuration The following shows a sample implementation of site-to-site IPsec VPN tunnel using a Cisco RV320 Gigabit Dual WAN VPN Router and a Cisco 2900 Series ISR. This short guide provides an example design for building a site-to-site IPsec VPN tunnel between a Cisco RV320 Gigabit Dual WAN VPN Router and a Cisco 2900 Series ISR. Cisco 2900 Series Integrated Services Routers (ISRs) provide services to meet the demands of today s medium-sized branches, support cloud-based services, and offer a wide array of common security features such as advanced application inspection and control, threat protection, and encryption architectures for enabling more scalable and manageable VPN networks with secure connectivity by Group Encrypted Transport VPN, Dynamic Multipoint VPN (DMVPN), or Enhanced Easy VPN. Cisco RV320 Gigabit Dual WAN VPN Routers deliver robust and easily managed VPN solutions to cost-conscious small business companies. This Smart Tip covers site-to-site (pointto-point) VPN, which provides an Internet-based infrastructure to extend network resources to remote offices, home offices, and business partner sites. #EASYVPN RV320 FULL#Different VPN topologies exist including hub-and-spoke, point-to-point, and full mesh. VPNs also integrate network features such as routing, Quality of Service (QoS), and multicast support. Security concerns may arise because of private data sent and received across public networks, but hosts encrypt all data using the IP Security (IPsec) protocol before sending through a VPN to allow staff to work from different sites without compromising the network. It enables a host computer to send and receive data across public networks as if they were a part of the private network. A VPN extends a private network between geographically separate office locations. A VPN exists as a private network constructed within a public network infrastructure, such as the global Internet. 1 print Article ID: 4938 Configuring a Site-to-Site VPN Tunnel Between Cisco RV320 Gigabit Dual WAN VPN Router and Cisco (1900/2900/3900) Series Integrated Services Router Objective Virtual Private Networks (VPNs) ensure business continuity and provide the ability to extend the corporate workplace to employees who need continual access to company resources.
