• hello i have a linksys wired router (BEFSR41) i recently got COD4 and had to change my dmz settings to play online. i was told to change my secondary DNS to and it has been working fine for a couple weeks. Out of the blue i am getting a DNS error and am unable to log in the playstation network. Help me plz
  • First off, get your DNS server settings back to how you had them before getting the advice of that secondary server. This should be matching what was given to your ISP.

    Why would you have to change your DMZ settings? if the Ps3 was there already things should have worked with no problems.
