ToHost problem

[powell molleti]

hi all,
 
 Humm with this configuration file i m able to 
 get the syn-ack replies for the syn to the fake0
 device , but they are being discarded by
 the CheckIPHeader element. I dont have a clue
 why.

 The following snippet from the file showed that

 frmlinux::FromLinux(fake0, 192.168.0.1/24);
  frmlinux -> frmlinux_cla::Classifier(12/0806,
                             12/0800);
  frmlinux_cla[0] 
    -> ARPResponder(0.0.0.0/0 1:1:1:1:1:1) 
    -> ToLinux;

  rmlinux_cla[1] -> GetIPAddress(16)
     -> ch :: CheckIPHeader() // ouput 0 , not
emitting
                              //    any packets
     -> IPPrint()
     -> EtherEncap(0x0800, internal:eth,    
                           internal_client:eth)
     -> intern_dev;

// This is CheckIPHeader second output , it is putting
// all packets here :(
// that means they are bad!, but why? !
     ch[1] -> IPPrint() -> Discard();
	 
it would be great if anyone throwed some light on
this.

thanks
cya
