So I will try to keep this as brief as possible but essentially in the past myself and others have used Hamachi to connect to game servers easily and it has always worked flawlessly have a while ago a tunnel to only one of my peers became consistently relayed, despite trying all the usual fixes including port forwarding etc the tunnel remains relayed, re-installing had no effect nor did trying the connection on another computer on the same network, I know that it is not a problem with Hamachi since we both have over tunnels to other peers that are direct and work flawlessly, I have in fact worked out it is something at my end, when trying to ping my peer I got a response however, when he tried to ping me it timed out after he had previously and successfully pinged his other peers furthermore he pinged the second computer I mentioned on the same network and again the request timed out. Evidently it is a problem at my end with my network, could anyone please help me with what the cause might be and how to resolve it. And before anyone suggests it for various reasons port forwarding for the game is unfortunately not an option due to other issues. Thanks for any and all help.
