Hi. Me and my friends use hamachi to play games with each other and recently my friend's tunnel became relayed. This caused massive lag for him, but my buddies didn't get any as they are direct. Since I'm unsure if it was me or him who caused it we both went through different videos/forums for an answer and did them. When he boots up his computer at first it says he's direct and after a minute it switches to relayed. I'm unsure what else I could do to try and fix it.
