Npc not giving out items?

I am having a problem... my ports where working fine until suddenly my internet go and my ports closed... it only appears that port 80 is open but in my router i have portforward the required ports to run maplestory server.

i am checking if my ports are opened at Open Port Check Tool - Test Port Forwarding on Your Router

and it only appears as if my port 80 was opened but they where all working before.

Sorry for my English <3
