VPNs are making broadband networking affordable for enterprises with large numbers of branch offices that need
to communicate securely with one another and to access resources at corporate headquarters or regional sites. Each
site—a franchise dealership,a medicalclinic, asales branch, or any satelliteoffice—simply connectsits localEthernet
LAN to the Cisco 1710 Router and establishes a secure broadband Internet connection through a cable modem or
DSL link.
The ability to offer managed VPN services to business customers, along with such value-added services as stateful
inspection firewall and remote management, can help service providers tap new services and revenue streams while
improving customer satisfaction. By deploying the Cisco 1710 Router to business customers, service providers can
extend their service demarcation point beyond the broadband modem to encompass a business-class security router.
High-Performance VPN
VPN performance is essential to ensuring that e-business applications deliver maximum performance. The Cisco
1710 delivers hardware-assisted VPN functionality allowing users to encrypt data using the strongest encryption
available, 3DES at wire-speed (T1/E1). Using high-performance VPN encryption and tunneling technologies, the
Cisco 1710 Security Access Router establishes a secure tunnel across the Internet to the corporate network. The
virtual network connection lasts only as long as it is needed, so enterprises no longer pay for idle capacity on costly
leasedlines. UsingtheCisco 1710, aVPN can scaleto support upto 100 concurrenttunnels or sitesin a fullymeshed,
fully secure global communications web.

Site-to-Site/Mobile User VPN
The Cisco 1700 Series routers support the Cisco Easy VPN Remote feature that allows the routers to act as remote
VPN clients. As such, these devices can receive predefined security policies from the headquarters’ VPN head-end,
thus minimizing configuration of VPN parameters at the remote locations. This solution makes deploying VPN
simpler for remote offices with little IT support or for large deployments where it is impractical to individually
