So what about Direct Access on SBS 2011?
“DA is supported in Windows Server 2008 R2, and as you will need a 2nd server to run it (You will need to put your DA server in a DMZ), then you can integrated this into a SBS 2011 solution). However we have no DA integration into the SBS 2011 Std console, so you would need to use the WS08 R2 guidence in deploying DA. “
Personally… this is a technology that you need to check vendor support. Quickbooks doesn’t support Direct Access, so test and deploy carefully.
