I have the router from hell. It's a SMC 7204BRA and have tried for hours configureing it with no luck. I even managed to block myself from accesing it in the end. I even tried to get ISP techsupport to configure it for me. They had no luck either, so I'm kinda out of ideas

i do get that brickwall, but still people upload from me just fine. Even files that only I have (I'm pretty sure) I use UPnP to connect and it seems to be working allright. Not perfect though and I would really like to change it but can't seem to find that extra cash I need
