4 Confidential 4 Who is Nomadix ? Nomadix is the leading global Subscriber Internet Gateway company. We manufacture dedicated networking devices using the Nomadix Network Service Engine (NSE). –Quickly and inexpensively get subscribers onto their networks without requiring client side software or reconfiguration of IP settings. –Generate more revenue per broadband connection through intelligent subscriber management and delivery of IP services. –Simplify their network infrastructure and maintenance costs. Nomadix gateways are used in almost 4,000 sites worldwide, with installations in USA, Japan, Asia and Europe. Provide Plug and Play More Revenues At Lower Cost 4,000

5 Confidential 5 Nomadix’s Value proposition Nomadix have several patents on public Broadband Internet provisioning, e.g. DAT and iNAT. These patents provide true ‘plug and play’ and support a complex of VPN links on a single hot-spot site. Nomadix, as an active member of Wi-Fi Alliance, has been instrumental in the make of the WISPr (roaming) “best current practices for WISP roaming” and Wi-Fi Zone concept. Nomadix established “license agreements” with leading industry partners, e.g. Proxim, Hughes Networks and Rockwell Collins for integration of NSE in application specific platforms. Patents WISPr OEM

6 Confidential 6 Nomadix’s Value proposition Nomadix functionality offered through the Nomadix Internet Gateways cover a rich set of features in the following main areas: –End User provisioning –Authentication (UAM, 802.1x Smart Client, 802.1x UAM) –Security (VPN, EAP) –Billing interfaces for both a centralized AAA and for local AAA –Roaming Through a range of solution partners, Nomadix fits well in a well designed end to end solution for carriers, ISPs and stand-alone sites. –AAA partners, e.g. Picopoint, Wificom –Roaming partners, e.g. Boingo, iPASS –HLR interface partners, e.g. Adjungo Networks Authentication End user provisioning Billing Roaming

11 Confidential 11 Plug and Play –No client-side software installation / reconfiguration –Dynamic Address Translation (DAT)™ For supporting users with: static IP Addresses, has a DHCP address from another subnet, going through public-private address translation Transparent Proxy. For supporting Browsers configured for Proxy or private DNS Server that could be behind a firewall VPN Support (PPTP and IPSEC) Support End-to-End security, even when user’s address is being translated. iNAT™ supports multiple VPN sessions going to same corporate VPN Access Server, even with limited number of public IP Addresses available. iNAT uses one public IP address for multiple sessions to different VPN Access Servers. Multiple Language Support –Pre-defined login screen in Internal Web Server End User Provisioning Features

12 Confidential 12 End User Provisioning Language Support All text viewed by the subscriber is entered in Web forms by the system administrator … … and placed automatically in user screens

13 Confidential 13 End User Provisioning iNAT™ and VPN VPN Firewall Authentication Server VPN Access Point Corporate Main Headquarter #2 ADSL Router Plus Firewall WLAN AP Nomadix HSG-25 VPN Firewall Authentication Server VPN Access Point Corporate Main Headquarter #1 WLAN Hot-Spot Corp #1 user 3 Public IP Address #2 iNAT™ supports multiple VPN sessions going to same corporate VPN Access Server, even with limited number of public IP Addresses available. iNAT uses one public IP address for multiple sessions to different VPN Access Servers. Corp #1 user 1 Public IP Address #1 Corp #2 user 2

14 Confidential 14 iNAT improves the connection success rate of multiple VPN tunnels to the same termination device Adjusts the mode of address translation depending on the packet type Optimizes usable public IP addresses by increasing their reusability (only uses them when needed) Uniquely supports users with static private (e.g x.x) or public (different subnet) IP addresses without any client IP setting changes iNAT - details

15 Confidential 15 Multiple DHCP pool and IP subnet support Subnets and DHCP pools assigned Location ID (e.g. via VLAN ID) Nomadix RADIUS VSA (‘Subnet’) Administratively assigned Multiple Subnet Support

16 Confidential 16 Save costs by using non-contiguous public DHCP pools –Example: Provide Internet access to 1,000 DHCP users and only have non- contiguous Class C pools, you can now define these separate pools in the Nomadix Gateway Use mixed pools (public/private) for varied network topologies and customer sets (residential vs. business) –Example: All residential users can get private IP address and be address translated, all business customers can get a public IP and not be address translated Differentiate your customers depending on their location –Example: All users in one building can be placed in the same VLAN and provision all their IP address from a dedicated pool Allocate different lease times to different users dependent on the peak usage patterns of the network Keep all devices (e.g. Access Points) on a separate public subnet that will not get address translated Multiple Subnet Support (con’t)

17 Confidential 17 Captive Portal –Pre-Authentication Home Page Redirection (HPR) Automatically redirect nomadic user to welcome page Multi-portal / multi-Service Provider support –Post-Authentication Page Redirection (HPR) Automatically redirect nomadic user to post welcome page Multi-portal / multi-Service Provider support IP filtering / access control White List for free/allowed sites Black List for blocked/restricted sites Presenting services –Up-sell Bandwidth / Public IP address –Personalizing services End User Provisioning Features Portal Page Service Selection Console
