We have a project that requires intercepting certain IP packets, modifying their payload, and sending them on their way. The modification is nontrivial, and so I think it would best be done in user space. Can anyone suggest a general approach for how to intercept packets, send them to user space, and then on to their destination? Should we look at netfilter/netlink? I'd like to avoid any kernel code.
