Unable to connect

Hey guys, I need a hand here, it's been about a year since I've played on Icecrown and decided to hop on to dust off the old druid. But on login I'm constantly getting a "Unable to connect" message.. I've double checked my password is correct (reset it as well), and I never had issues with this build connecting before, again, about a year ago.

It's possible my internet connection setup has changed, but I don't remember having to set my ports originally. If anyone can link a detailed port forwarding tutorial, I can give that a shot, barring any other suggestions?

Cheers!

EDIT: So it turns out my realmlist was wrong, it was set as "logon.warmane.ru" instead of .com... odd. Did the server change over the past year or so?

Either way I'm back on, please disregard. :P
