I've been a big fan of LTT for years now but never joined the forums until now cause i've kept things pretty simple. But i've herd Linus say time and time again join the forum to ask questions, as there many tech literate people here able to help.
So the real basic bones of my problem is that I have a router provided by my ISP and they have set it up so it's completely inaccessible by putting in my IP address into a url on any system in my home. This had made it so i can not set up port forwarding for say, minecraft server hosting, as an easy example. I've never bought a router or modem before and am not entirely sure what to buy or how to set it up in my home but the goal is for the normal router to stay as is and be the wifi access point of the house while i have a 2nd one that i can hard wire to and set up port forwarding and such. I don't know much on the hardware of this. What i do know is i had a friend who works for IBM as well as two other friends who are in computer science all try to access the ISP provided router and all fail cause it is totally locked out, inaccessable.
Any help would be greatly appreciated as well as advice and i will try to be very quick to reply back to any questions if i need to provide more information.
