depending on what your network is using for protocols. for instance pptp and l2tp are vpn protocols. you likely wont need unless you get outside access in.
direct parallel i also doubt since you likely use a network card for your lan. your intel r pro, is your network card, yes you should keep.
this is general i know, but i dont know your logical topology. if there is no reason to dump them, leave them.
thats my advice anyway.
