PPP over Modem

If you are sure the client has installed the PPP link as default gateway, is the client otherwise connected to a LAN? If the client is connected to a LAN and the best route is to the LAN, the

PPPlink will not be used. The following figure illustrates this case. The client will always direct all packets bound for 10.0.0.10 down its Ethernet connection. This will occur regardless of the PPP gateway setting and possible lack of connectivity in the Ethernet cloud.

Figure 164: Gateway Collisions

If you need to make a temporary connection to the server, disconnect the LAN. Otherwise you must connect to the server at its PPP assigned address.

Problem Four

I can ping the server, but not any of the devices it is connected to.

Each of the devices you connect to must have a default gateway setting that points at the local PPP link address on the server with the PPP connection.

Problem Five

I am having performance problems.

What connection speed did the modems negotiate? Are there line quality problems?

What sort of traffic is traversing the PPP link? Is it being saturated with HTTP, FTP or TFTP traffic?
