Remote Node TCP/IP Configuration
This chapter shows you how to configure the TCP/IP parameters of a remote node.
A typical LAN-to-LAN application is to use your Prestige to connect a branch office to the headquarters, as
depicted in the following diagram.
5.1 LAN-to-LAN Application
Figure 5-1 TCP/IP LAN-to-LAN Application
For the branch office, you need to configure a remote node in order to dial out to the headquarters.
Additionally, you may also need to define static routes if some services reside beyond the immediate
remote LAN.
5.1.1 Editing TCP/IP Options
Follow the steps below to edit Menu 11.3 - Remote Node Network Layer Options shown next.
In Menu 11.1, move the cursor to the Edit IP/IPX/Bridge, then press the space bar to toggle and set the
value to Yes. Press [ENTER]
to open Menu 11.3 - Network Layer Options.
There are two versions of menu 11.3 for the P642, depending on whether you chose VC-based or LLC-
based Multiplexing in menu 11.1.
VC-Based Multiplexing
Remember that for VC-based multiplexing, by prior mutual agreement, a protocol is assigned a specific
virtual circuit, e.g., VC1 will carry IP, VC2 will carry IPX etc.
