Service Components
iPass enables your remote users to dial into and use the Internet access networks of the top-tier ISPs and telecommunications carriers around the world. There are two key service components - the iPass RoamServer software and the iPass client software.
  • iPass RoamServer is a small software application installed in Netalliance's infrastructure. RoamServer works hand-in-hand with our existing user directories to minimize administration, maximize security, and give you control over which users can access the service.
  • iPass client software is an application that installs on the laptops of your remote users, giving them a simple point-and-click interface for dialing into the worldwide access numbers. When a remote user dials into one of these networks, iPass technology at that network access provider, securely routes the user authentication request to your company for authorization. When a remote user connects to the Internet through iPass, it takes just a few moments to get connected and the steps are transparent to the user.

The iPass Transaction Flow
More detail about how the iPass service works is available at the end of the Corporate Remote Access Alternatives white paper.
  • The remote user dials into a local iPass access point through an iPass-enabled network access provider (local ISP).
  • The iPass software on the server at the local ISP encrypts the user name and password and forwards it over the Internet to an iPass Transaction Center.
  • The iPass Transaction Center routes the encrypted user information to the RoamServer at Netalliance's site.
  • Netalliance's RoamServer sends back a "yes" or "no" authorization response to the local ISP, via the iPass Transaction Center, allowing or denying the user connection to occur.
  • After receiving authorization, the local ISP connects the user to the Internet. If the you use a VPN solution, the remote user can initiate a secure session to securely access internal corporate resources.
  • When the user disconnects, iPass logs the service usage. At billing periods, iPass pays the network access providers for the use of their networks and provides call detail records and usage to the iPass Solution Partners, so they can bill their customers using the service.

VPN Interoperability
The iPass Corporate Access service integrates well with all major virtual private network (VPN) technologies to enable telecommuters and business travelers secure communication and access to their internal corporate networks.

iPass has created brief marketing notes on "proven" VPN configurations with some of the industry's leading VPN solutions. iPass continues to do VPN testing and develop new tech notes so if you are interested in knowing about interoperability with other solutions, please let us know.
