    Lightbulb help : about tcp data encrypt!

    Now , I'm working under Linux7.2(kernel 2.4.9)
    and I want to encrypt all transfer layer data with my own encrypt functions.
    And let the Lan computers communcate under a VPN like envrionment.
    I use the nf_register_hook(..) function to register a module function under netfilter
    to get the transfer layer data and encrypt/decrypt them. but when I do this, the kernel allways panic. I don't what's going on?
    do I give the wrong checksum, or the skb must be clone to operate?

    somebody can help me???? thanks a lot!

    now may be just a user defined encrypt/decrypt function. to encrypt the transfer layer data to confuse sniffer tools.
