[Click] need help with click

[Manan Chandra]

hello Dr. Kohler,
I am a graduate student at New York University. I was wondering if you can answer my questions regarding Click modular router.
I want to run a click program on an NFS client machine to capture packets meant for the NFS server, and then after some delay sends them to the server.

 Below is the short code that I am using.
  tun0::KernelTun(137.99.10.193/31, MTU 1500, DEV_NAME wan0);
  tun0->NotifierQueue->ToDevice(eth0)
the IP address of the server is 137.99.10.192 .

 this is the output of route
 Destination        Gateway         Genmask           Flags   Metric   Ref    Use  Iface
 137.99.10.192      *               255.255.255.254    U            0      0        0      wan0
 137.99.1.0            *               255.255.255.0        U             0      0        0     eth0
 default         137.99.1.1         0.0.0.0                    UG          0      0        0     eth0


 But I am not getting any response from the server. It would be of great
 help if you could tell me how to trap the packets meant for the server
 with IP address 137.99.10.192, store them in a click element for delaying
 them. And then sending the packets to the server over the network such
 that the client recieves the reply correctly.

 Sincerely,
 Manan
