If you want to further customize and optimize your connection, refer to Chapter 6, "Advanced PPP Configuration,” for the following topics:

• Configuring data or header compression
• Configuring MRU parameters to adjust the frame size
• Configuring call retry and timeout parameters
• Configuring matching inbound and outbound authentication
• Configuring other inbound call options
• Configuring interface physical options

Before your WAN connection works, you must also complete the following tasks:

• Configure network protocols that will run over the WAN connection. These might include the Internetwork Packet Exchange^TM (IPX^TM) protocol, IP, and AppleTalk.
• Bind the network protocols to the configured WAN interfaces.

For information about these two tasks, refer to Chapter 8, "Configuring IPX,”; Chapter 11, "Configuring IP,”; Chapter 12, "Configuring AppleTalk,”; and Chapter 14, "Configuring Source Route Bridging.”
