Microsoft announced it would stop selling TMG in December as part of a series of Forefront product changes. Essentially, TMG isn't.

Under each of these keys create new keys called Client and Server. Files larger than 1 GB may take much forefront tmg 2010 to download and might not download correctly. You might not be able to pause the active downloads or resume downloads that have failed.

The Microsoft Download Manager solves these potential problems. If you do choose to install antivirus software on the TMG virtual machine, be sure to closely follow the guidance set forth by Microsoft for using antivirus software on TMG, which can be found here. This can only be accomplished using PowerShell, however.

Here we can specify how long objects will live in the cache. Here we can specify how long objects downloaded via FTP will live in the cache.

Figure 9 The Advanced tab is used to configure a limit on the size of objects in cache. This will prevent large downloaded files from consuming forefront tmg 2010 amounts of cache.


In addition there is an option to Cache SSL responses. This applies only to bridged SSL traffic from web publishing rules.

Summary It was a sad day when Microsoft announced that they were abandoning the future development of the Forefront TMG firewall. It is widely deployed, and in my opinion was one of the best solutions for protecting Microsoft networks and workloads.
