I have installed TMG 2010 SP2 at Windows 2008 R2.
So, as I read TMG blocks as broadcast as multicast.
And such built-in only one way default behaviour is not right.
I want in my own (as user/admin) define whether it is necessary to me or not as following there have to be ability to switch it on/off such option, for example as checkboxes for each network (address range) defined by default/user - one for broadcast and one for multicast.
So, please add such functionality to kernel mode driver and to service in the next nearest SP or rollup.
And/or tell how is it possible to switch it on at Tmg 2010 SP2 and later.
There are some important services relying on broadcast: NetBios, Dhcp, some Alladin hardkey protection, some special soft.
If somebody of MS techinians will send registry parameter for this or specially designed driver, all will under my responsibility only.
