I hope you can help. We are currently moving and SL installation of SL for a client of ours and also upgrading to SL 2011 SP2 (from FP1) and deploying the Web Apps CU1. The SQL Server and the SL Server will be behind a firewall (along with all databases, including BP and SharePoint). The Business Portal will be on a seperate server in a DMZ.

Could you advise best practice regarding deployment of the Web Services IIS site and the Web App IIS site with respect to the DMZ please. The solution will be serving users across EMEA and ASIAPAC in multiple companies. Any adice will be greatly appreciated.

You can contact me directly at kfinn@n2end-it.com if you wish.

Thanks in advance
