When implementing Internet-based client management in Configuration Manager 2007 with ISA Server, you may run into ISA configuration issues--and many of you out there have. While we do our best to document everything we think you'll need to know to be successful ConfigMgr admins, some things are just beyond our control. I know we recommend bridging over tunneling, but I know about as much about that as building real bridges and tunnels :-)
There are many ISA Server-related resources out there to help you if you get stuck. For ISA-specific information, you can peruse the ISA Server documentation online and the ISA Server newsgroups. For help with Internet-based configuration, check out the Configuration Manager Internet-based client management documentation and if you're trying to get ISA bridging to work, check out how Adam (one of our testers) got this working.
Still have questions? You probably already know that there is a documentation feedback e-mail alias for SMS/ConfigMgr (email@example.com), but did you know that there is one for ISA Server as well (firstname.lastname@example.org)? For questions and concerns for how to configure ISA for use with Configuration Manager, send your feedback to both aliases (smsdocs and isadocs) at the same time, which will allow the appropriate team to answer your questions about the products they know and love.
