Okay to start off i'm running a linksys e3000 with the latest firmware and i have put in my computers ipv4 into both single portforward and regular and saved. When i go check if my ports are open through a website it only shows my external ip and also tells me my ports are closed for the MC port 25565. Now this is where i can't figure out what's wrong, I have added those ports into the computers firewall aswell and when i run my minecraft server it binds but only i can connect. So i know something is wrong with the ports. Someone told me i have to make a static ip but my dynamic doesn't change for the computer so i don't see the need, i also don't see an option for that in my router
