I'm not actually seeing any restrictions based on the IP from which you're posting, either of you.

If you are unable to connect to Battle.net, this issue can be caused by several different things.

If you are using Windows 2000/XP/Vista/7 please first verify you are playing under an Administrator Account. Some user accounts can be restricted to save the information needed for the games connection and this can cause the connection problem. To find out which user accounts are marked as Administrator accounts, please see the instructions below:

-Click Start > Control Panel and look for an icon called User Accounts.
-Double click this and it should bring up a list of users on your computer.
-Find the user account that matches your user name and have a look in the group column, it may say administrator, power user or user. This is what type of account you are logged on with. If it says administrator you should be ok.

For Windows Vista/7, in order to set the game as Administrator Mode, please follow the steps below:

1. Right click on the game icon.
2. Select "Run as Administrator"

Also make sure you are not running any add-ons or modifications of any kind. These have also been known to cause connection issues. If such programs exist please completely remove them from your system. In some cases you may need to reinstall the game. If the issue continues please try each of the steps below.

Step 1:
Check for Updates:

* If you have not yet patched the game, please download and install the latest patch from the Patch page - ("http://www.blizzard.com/patches").
* If you have a router and are having various internet connection issues, please check your router manufacturer's website for any updates.
* For any information regarding server maintenance, please check the Battle.net Status Forum - ("http://forums.battle.net/board.html?forumId=12019&sid=3000http://www.battle.net/forums/board.aspx?ForumName=battlenet-status").
* For information about current connection issues, please check the Technical Support News Page - ("http://www.blizzard.com/support/").

Step 2:
Temporary Restrictions:

Please try to connect to all four Battle.net Realms (USEast, USWest, Europe, and Asia). If only one Battle.net Realm is inaccessible to you, then it may just be a temporary connection problem or a temporary restriction. Battle.net access may be restricted for one of the following reasons:

* Spamming text in the chat channel (often associated with bots)
* Rapidly connecting/disconnecting to Battle.net (often associated with bots)
* Repeated attempts to use an invalid CD-Key or an incorrect Battle.net password
* Repeated use of third-party programs (hacks) - these include but are not limited to sending bad packets, flooding the server(s), and the use of hack programs

Step 3:
Battle.net Server List:

Your Realm or Gateway selections may have been altered in some way. This will prevent you from connecting to a Blizzard Entertainment Battle.net server. For instructions on restoring the correct server list for Diablo II, Warcraft II, and StarCraft, please go to this page ("http://us.blizzard.com/support/article/21138").

Step 4:
Internet connection notes:

Firewalls, Routers, and Internet Connection Sharing

* If you are using any type of firewall, router, or you are sharing your internet connection between several computers, you may need to set your system up to allow access to Battle.net. For instructions on setting up your connection, please visit our Networking Help page - ("http://us.blizzard.com/support/article/21086").

Test your Internet connection:

* Use the Telnet command to make sure your Internet connection is running smoothly. You can find more information on our Telnet page - ("http://us.blizzard.com/support/article/21139").
* Use the Trace Route report to help identify if and where a problem is happening. You can find further information on our Trace Route page - ("http://us.blizzard.com/support/article/21140").
* Use the NSLookUp command to check the connection. You can find further information on our NSLookUp page - ("http://us.blizzard.com/support/article/21141").

Step 5:
Background Applications:

You may need to exit any programs you have running in the background to improve network performance and stability.
