Initially I was having an issue connecting to my friends Minecraft server. Upon using the Diagnose option for his node in the network, I saw that both were blocking inbound traffic.
I then proceeded to add Hamachi to my Firewall which resolved the issues for the local node. I also requested he do the same, which has done yet we can't seem to get Hamachi through his Firewall.
Both of us are running Windows 10. He's already tried combinations of restarting the hamachi service, removing and re-adding Firewall rules for Hamachi, and reinstalling.
Nothing seems to be working...
Any suggestions or is this a known bug in Winows 10?
