You need to have the following in your .CSDEF file
<Setting name="Microsoft.WindowsAzure.Plugins.RemoteAccess.Enabled" value="true" />
<Setting name="Microsoft.WindowsAzure.Plugins.RemoteAccess.AccountUsername" value="s093294" />
<Setting name="Microsoft.WindowsAzure.Plugins.RemoteAccess.AccountEncryptedPassword" value="{encoded password" />
<Setting name="Microsoft.WindowsAzure.Plugins.RemoteAccess.AccountExpiration" value="2014-05-01T23:59:59.0000000+02:00" />
<Setting name="Microsoft.WindowsAzure.Plugins.RemoteForwarder.Enabled" value="true" />
and in your .csdef file:
<Imports>
<Import moduleName="RemoteAccess" />
<Import moduleName="RemoteForwarder" />
</Imports>
The easiest way to add it is from visual studio when packaging/deploying.
