I wrote such a tool[1] for my own use some years ago. It uses libpcap to grab all the packets on one interface and then re-emit them from another interface after some delay, with optional packet loss. If there’s real interest I could dust it off… maybe rewrite in Rust. [1] https://github.com/chrismerck/lagsim https://github.com/chrismerck/lagsim
