I'm trying to clear port 25565 for a minecraft server I want to set up, but I'm not having any luck with any solutions I've found as of yet. I have a phone line connected to a modem/router which is connecting to a more powerful router and then hard-wired to give the nearby computer giving it internet in addition to the wireless that both the first and second routers provide.
I realize I need to simplify this entire operation, but I also really want to find out how to clear port 25565 for minecraft to work. Any help would be appreciated.
