[Sis-SCPS-INTEREST] SCPS-NP help

[=?gbk?B?d2R5?=]

Hi all:
    I am a student,I was learning to use SCPS¡£So I refer to the document¡£I would like to build a  simulated environment£¬such as£º
   A-----GATEWAY---- B

the PC A  as ground host£¬I run the SCPS-FP client on it¡£ so I think PC A should send  NP over IP packet to gateway¡£when the gateway receive a packet from A,It should removed the Ip head and send to B.
       FP                                     FP
   A  TP     ---- GATEWAY------- TP B
       NP           NP         NP         NP
       IP            IP          LINK      LINK
       LINK       LINK

 
when I configure the gateway use fllow configure£º

    ./configure --nl_default=np --gateway=yes --tap=yes

the gateway work not well¡£It not removed the Ip head and send to B


   so  I need some help for use the SCPS-NP. I hope you can help me.

I would be very gratefue if able to provide an example about use the SCPS-NP¡£
     Best Regards!
