There are several Realms in which to play Diablo II. We work in all of them. Europe, US East, US West, and Asia. When playing in a realm it is necessary to select the preferred realm prior to selecting the Battle.Net button to connect to a server. Follow these instructions to change your selected realm.
When the Gateway selection screen opens the current gateway will be highlighted with a grey bar.
To select a different gateway just click on the gateway you want.
Confirm, that you have selected the proper gateway by looking for the grey bar on the "Select Gateway" screen. If the proper gateway is selected press on the OK button.
