1. WholeSale Model 10

2. WholeSale Model This feature enables the Nomadix device to act as an L2TP Access Concentrator (LAC) and initiate single or multiple L2TP tunnels to different L2TP Network Servers (LNS). The L2TP Tunneling feature makes use of the existing ISP infrastructure that is similar to the one used for dial-in customers which involves tunneling PPP (Point-to-Point Protocol) packets using L2TP. This can be very effectively used with the RADIUS realm routing feature to initiate tunnels based on the user realm information and route realm specific traffic to a private network specific to that realm. Optional module 10

3. Multiple ISP Tunnel Support 10

4. WholeSale Model Only one L2TP tunnel needed per ISP.Per User PPP session going through L2TP tunnels to respective ISPs. PPP Sessions initiated on User Login via Gateways portal/Login page. Tunneling based on “Realm” ( prefix or suffix ) specified in the username. Tunnel parameters retrieved via either RADIUS request or pre-configured in HSG. PPP authenticates and specifies IP address for the user. iNAT translates each subscriber’s private address to one provided by own ISP 10

5. Gateway Setup 10

6. Gateway Setup Tunnel profiles can be defined when L2TP tunnel parameters are known and it is not necessary to send an access request to a Radius server to obtain those parameters or for accounting purposes. Create a tunnel profile for each L2TP tunnel whose parameters are known. The tunnel parameters that the profile contains are the IP address of the LNS and the tunnel password. 10

7. Gateway Setup 10

8. Gateway Setup The HSG Radius client must be setup for realm-based routing mode since realm information will be used by the Gateway’s L2TP tunnel feature to determine how to handle usernames that contain realm information. 10
