For SSL-enabled Web applications, TMG decrypts the client’s request, inspects it, and terminates the SSL connection with the client computer.

SSL bridging protects against attacks that are hidden in SSL-encrypted connections. TMG before we forward it to the published Exchange Server by terminating the connection at the TMG. By using certificates, we can analyze the session at Hence it is essential to ensure that traffic is encrypted using SSL. This can be potentially unsafe if anyone runs a network sniffer over the wire and can therefore see user names and passwords. Certain authentication mechanisms, such as Basic Authentication, allow user credentials When you publish Exchange client access with TMG, communications from external clients and from TMG itself to the published server can be encrypted using Secure Sockets Layer (SSL). the default paths configured after running the New Exchange Publishing Wizard. This is done via the Exchange Publishing Wizard, which is discussed in the next section. When the administrator has decided which client access methods need to be made available, access to certain folders needs to be allowed through TMG. Of course users with mobile devices capable of ActiveSync can access their mailboxes using Exchange Active Sync (EAS). Their mailboxes, or they can use RPC over HTTP over the Internet to check e-mail via Microsoft Outlook. Users with laptops can either use Outlook Web Access (OWA), which is lightweight and available via a Web browser to access In the following figure, I have illustrated a typical Exchange 2010 design that include Forefront TMG 2010.Īllowing client access, you need to understand and plan what client access methods you need to make available on the Internet for your end users. Create proper policies in TMG to allow https, POP3, IMAP, SMTP traffic securely to Microsoft Mail clients.

There are few consideration you must take into account such as placing of server in different network segments. The main purpose of these deployment is to improve performance for client access, secure client access and encourage utilization of best practices of Exchange, TMG, and the Exchange clients (Microsoft Outlook) involved. you need to plan and deploy the different roles of Exchange Server which includes Exchange HT, CAS, ET and Mailbox and publish in Forefront TMG 2010. To ensure that every Exchange client access mail securely from anywhere (internally and externally) Exchange deployment published through Forefront TMG 2010.
