如何架設Multi-session PPPoE server

[IRIS0621]

因為測試需要架設一個PPPoE server模擬日本ISP所提供的服務,
一條線可以有兩個帳號同時連線.
但是我只會架single的PPPoE server,
有沒有人知道有什麼軟體或套件可以模擬這樣的環境?
不管是在windows server或linux系統上的都行!
請各位大大幫個忙,小妹感激不盡....!!

[FYI]

pppoe-relay(8): user-space PPPoE relay agent - Linux man page
PPPoE - Roaring Penguin Software

HOW TO set up a RASPPPoE Server

Limitations

Windows 2000 Professional allows only two such connections to be in place simultaneously. Windows 2000 Server (and higher) supports more than two simultaneous RASPPPoE connections.

NAT32 supports up to 8 such connections.
