Hey Ben,
Thanks for the contribution! Looks good in general, I've added some comments here an there to make it work with the current conventions (especially given Option<T> in config structs). Also, please run the following to ensure that CI checks will pass:

• cargo fmt
• cargo machete
• cargo sort --workspace
• cargo clippy --all-targets --all-features -- -D warnings (unless you use MacOS, as there might be some TCP related warnings which do not exist on Linux).
• cargo test or cargo nextest run

@BenFradet remove the hash and number from commit message title and preferably squash everything into one commit ;)

There's test that needs fixing:

I moved the ipv6 setting up to the tcp config as it was making more sense to me
