Call of Duty modern warfare 3 server is not available

Hi, I try to play CoD MW3 the first time and show me that error. I put my computer in DMZ, disable comodo antivirus/firewall/antispyware, the windows firewall and the error continue.

Ports scanners say that ports in my computer is opened, I 've checked the local game installed (check local cache of game option in steam) and delete the folter appcache in steam folder. Nothing of that works.

make sure your network config has port fowarding on, this happened to me to yesterday it was the whole network so dont worry

Restart your router or modem and try again.

Thanks for answers.

CarbonatedKlenix: I was tried the port forward for all ports needed, and as other option I put my computer in DMZ (is more "opened" that port forward), ports scanners said that ports in my computers is openeds, but the game not connect. Monitoring connections in Comodo Firewall connections in this time is open.

GmF|Danger: I've restarted all several times... Computer, modem, router, put the modem as bridge (ADSL... only 2Mbps, I'm from Brazil...), only not tested play in other computer... that I will test in next weekend...
