Sadly, There's no "Enable port forwarding". I can enable/disable each forwarded port. All of them are enabled. But I have there some "DMZ Host". I don't know what it is (I attached a screenshot), but another idea came to my mind. Can be relayed tunnel cause by router's firewall? I can't turn it off anywhere, but there is this DMZ Host.
Also, I tried static routing. I don't know, maybe I've set some weird non-working crap but what do you think? Screenshot
Exactly same problem for me!!! on my last router the connections with all people were Direct but ever since i got a new router cause it was faster and to keep up with technology and because our service didnt support the old one anymore i have had a relayed tunnel with EVERYONE and they have had relayed tunnel with ME ever since
this may seem not that good but i wanna help a little bit. Just invite your friend over with a laptop or go to his place and help him get his tower and other stuff to your place. Make sure you have enough ethernet cables and enough plugs in the wall to cover his pc and just play it like that :) but i know it is painful and will get annoying over time
i finslly got the direct connect and played like two good games of arma 3 with a buddy then had a win 10 update an its screwed my tunnel up ive re installed hamachi all the above with ports on my router ive even erased an re entered them again added the firewall stuff and i can not get the direct tunnel anymore is anyone still on this thread i need help lol bad
