Remote VPN Access
  • What does it enable you to do?
  • Network-based solution provides secure connection to your network
  • Connects off-net locations/users from almost anywhere
  • ISP independent, uses any Internet access – dial-up, DSL, cable, DIA, etc.
  • Seamless integration with FR/ATM and IP VPN services
  • Leverage IP Gateways in GC IP VPN
    • Backup IP Gateways can be selected for redundancy & resiliency
  • Security via IPSec encryption using 56- or 168-bit 3DES
    • Secure tunneling over the Internet to IP Gateway to GC IP VPN
  • All traffic marked as Basic, and billable under the usage model
  • Only available to Layer 3 VPNs
  • Two options: Mobility (Existing) & Site (NEW)
remote vpn mobility access options
Remote VPN Mobility Access Options
  • Software-based client, single laptop/desktop
  • For remote or mobile single-users
  • Hosted RADIUS AAA server option– network-based authentication w/ redundancy
  • Split tunneling not supported from Client
    • Ability to have a tunnel to the corporate WAN and still access the Internet or local resources via the local connection
  • Two Billing Models
    • User Reservation Model - Per Concurrent user (Per Tunnel)
      • Tunnel speeds: 56Kbps, 128Kbps, 256Kbps & 384Kbps
      • 10-1,000 in increments of 10 concurrent users (tunnels); Maximum of 1,000 concurrent users
      • All Tunnels must be the same size within a Domain (or Realm with Hosted Radius)
      • Multiple regions can be selected
      • Innovative “over-booking” economics
    • Bandwidth Reservation Model – reserve bandwidth to be shared among multiple users
      • 1 Mbps increments only up to Maximum of 45Mbps Reservation per Port (Instance)
      • Maximum 1,000 Concurrent Sessions per instance
      • Maximum tunnel size = port, TCP controls flow rates as new users connect (tunnel balancing)

Hosted RADIUS For Remote VPN Access
  • What is it?
  • Hosted (Managed) RADIUS AAA server for authenticating Remote VPN Access users (mobility option only)
      • Can only be used to authenticate services - uses user name and password
  • Leverages carrier’s-c AAA servers hosted in network
      • Multiple mirrored devices deployed in network for redundancy
  • Can purchase multiple Domains on the AAA server – MRC per Domain
      • Unlimited users per Domain & low cost MRC per domain
  • Customers use online self-service portal to add, change and delete users accounts
  • Benefit(s)
  • Customer no longer needs to support RADIUS server on site.
  • Eliminates onsite RADIUS security concerns & provides redundancy.
remote vpn access site option
Remote VPN Access Site Option
  • Hardware-based, single location, multiple PCs (LAN)
    • Suitable customer provided CPE (supported/tested: IPSec capable)
      • Cisco & Nortel
    • Split Tunneling from CPE SUPPORTED
    • Each site MUST have it’s own Remote VPN Access (IP Gateway Port) allocated
    • 1 Mbps Increments up to Max of 36 Mbps (throughput) per Instance (port)
    • Provider integrates IPSec- & MPLS-based IP VPN solutions
    • Billing – Bandwidth Reservation Model only - purchase bandwidth per Port
    • Support for existing IP VPN performance SLAs
