I have a pc that shares internet connection to another device, which is configurated to access it's manufacturers website and get any updates available. Note that this internet sharing is made through my ethernet port and that the device isn't configurable to access any other website.

Are there any methods to get all the data that is passing through my ethernet port and then connect my pc to the device and reproduce exactly what the website sent to the device when I recorded it like making my pc the website?

An Example:

• Device x Website

  
  
  
  
  
  • device : get the website ID
  
  
  • site : 0000000XX0Xx00xx0
  
  
  • device : get date and time
  
  
  • site : 12:30.31-12-2011GMT-4
  
  
  • device : download updates if available
  
  
  • site : pkg1.zip pkg2.iso pkg3.tar
  
  



• Device x PC

  
  
  
  
  
  • device : get the website ID
  
  
  • pc : 0000000XX0Xx00xx0
  
  
  • device : get date and time
  
  
  • pc : 12:30.31-12-2011GMT-4
  
  
  • device : download updates if available
  
  
  • pc : pkg1.zip pkg2.iso pkg3.tar
  
  

So just reproduce the same thing the website sent to the device, but it'll be my pc that will be sending the data.

Thanks for the attention, Rodrigo.
