Greetings,

Thank you for your follow up e-mail.  I understand that battle.net has been locking your account when changing location or accessing from a different IP.  This is the intended functionality of battle.net to prevent possible exploitation or compromise of accounts, however, we realize this can sometimes negatively affect accounts of players who travel often or use lower ping/tunneling/proxy services.

Unfortunately there is no way for us to set up an account to access from the number of IPs used by such services as they change nearly every time they are used to allow for the best connection.  Fortunately to unlock an account after this type of action all you need to do is change your password.  If this does continue to be a problem though, I would recommend checking our Tech Support forums for possible workarounds or alternative options to reduce latency or lower ping.

Please feel free to write back to us if you have any additional questions or concerns, as we would be more than happy to assist you.  Thank you again for your feedback!
