I was very satisfied with my router until i for some reason thought I'd do a firmware update. I put in v 2.30 and since then, the router has just been awful. It completely ignores my portforward/DMZ/virtual server settings and it seems to also restrict my ports more than before, for instance modern warfare 2 tells me my NAT type is strict when it has been open every time before the firmware upgrade.
So i looked for new firmware again and found 2.34. Sadly the problems persist. How can i solve this? Can i revert my router back to 1.06? (which I've heard is the latest working one)
