I'm having problems

So i made a pserver. Just a plain club559. Put my hamachi in all the right places. Used Yogda to change client to (Hamachi Ip):8888 and yet i'm the only one that can join. This is really peculiar because this isnt supposed to happen. I have never owned a pserver previous to this so it is not something that just happened.

Your firewall might be on. Turn it off.

it worked good sir thank you
