hello guys!! i just want to seek help specifically, if possible, can you give me a detailed step by step process about port forwarding??

i've been trying to do this myself but i end up on sites where i can't understand how to do things. maybe you can offer me layman's steps so i can fully understand what i have to do.. please forgive me, i'm really not good at this things.

i will greatly appreciate your help guys.. thanks..

If you have a modem/router that is firewalled & need specific advice for that device...have a look at what devices are plugged into your computer. What boxes plug into your computer & allow you to connect to the internet??? Look for brand name & model number. If you can't see anything, turn the device over & have a look underneath
