Hello could anyone help me a bit (like giving an tutorial)
On how to intercept a certain packet from being send from my computer to another
end make my program send a modified packet instead
I searched google but couldn´t find anything usefull so I´m asking it here
Thanks in advance!
Why do you need it? :confused:
FYI: I wouldn't like that some "unknown" program changed the data my App sent to another PC! :mad:
Its for a game the game sends a md5 salt in a packet to the server I need to intercept it and change the value of the salt.Quote:

What "bump"? :confused:
Don't you understand that no one here makes what you want to implement?
hello,
well packet filtering could be implemented by various ways it could be in the kernel or in the user mode. basically for user mode filtering the best unknown technique is implementing LSP (layered Service Provider) . there are couple of examples at MSDN as how to implement the LSP DLL.
moving to kernel, it could be done at various level depending on your requirement. it could be a TDI (transport device interface ) filter. or may be a NDIS filter.
but since you only want to modify the content of the packet. you could use LSP.
