Hello, I port fowarded ports to use Tunngle, and it worked for me. Then when my brother installed it, I made a new port thing with same ports, and assigned it to my brother's PC. But on Tunngle, it said it didn't work for him. And it didn't, because he can't see most people. This is the first time I have port fowarded the SAME ports to two devices. So I assigned the ports on me, and then unassigned it on my brother, then assigned on my brother only, and it worked for him. Then I assigned it to me, and it didn't work.
How can I assign it to two devices to that it'll actually work?
