I am using ip_queue. I understand that is depreciated.
I want to intercept a packet, alter it (change payload and source ip

have it continue on its way to another machine. However it never
shows up at that other machine. Is there anyway to do this without
doing an NF_DROP and then sending a new packet through?
Will libnetfilter_queue do this for me?
Yes, but you will have to compute the checksum of the modified packet by
yourself.
Someone should send a patch which adds helper functions to ease that
task in a day or two.
That makes sense. It would also allow to take advantage of hardware
TX csumming.
