User space tproxy implementation

Question

I am using the tcp / ip stack for user space for a specific application.

I saw Tproxy support as a kernel module in the Linux kernel stack.
But I need a similar implementation on the user space stack.
So that I can find out the current tproxy internal work. Someone help me implement it in User Space or please explain the internal work of tproxy material, I mean “packet labeling”, “twisting destination IP addresses in the incoming and outgoing stream”, “saving all this in the internal structure of the table ", etc..

Thanks in advance.

The kernel documentation for TProxy is still the best source. Otherwise, google breaks out a bunch of results for tproxy documentation and tproxy example .

There are also projects supporting tproxy. For example, Squid Proxy supports it and a rather long wiki page about it.
