You have virtual Ethernet set up across four logical partitions. You want selected logical partitions to share a modem to access an external LAN.
You are the system administrator at a medium-sized company. It is time to update your computer equipment, but you want to do more than that; you want to streamline your hardware. You start the process by consolidating the work of three old systems onto one new system. You create three logical partitions on the system. The new system comes with a 2793 internal modem. This is the only input/output processor (IOP) you have that supports Point-to-Point Protocol (PPP). You also have an old 7852–400 electronic customer support modem.
Multiple systems and partitions can share the same modems for dial-up connections, eliminating the need for each system or partition to have its own modem. This is possible if you use L2TP tunnels and configure L2TP profiles that allow outgoing calls. In your network, the tunnels will run over a virtual Ethernet network and a physical network. The physical line is connected to another system that shares the modems in your network.
The following figure illustrates the network characteristics for this scenario:
System A must meet the following setup requirements:
System B must have the licensed program and relevant components of iSeries Navigator installed: iSeries Access for Windows and iSeries Navigator (Configuration and Service component of iSeries Navigator) V5R2, or later.
