Hi,

Recently my company has taken over the IT support for an educational facility.  We have had them shift to the office 365 service from Microsoft, removing the need for an on-premise exchange server to align with their IT strategy of having as many services hosted in the cloud as possible removing those dependencies on the local network setup - this is because they get poor internet speeds and have many remote sites around the country, so having services in the cloud works in that regard.  

It would seem now that TMG does not much more than forward ports that are already being filtered by the router.  On top of that i have a feeling that the TMG is misconfigured to the point of screwing with the internet and speeds (this is one of the major issues there).  Ive not been able to identify a misconfiguration item, but in speed tests from the TMG server with no one else connected as opposed to in front of the TMG server, the latter is about double the speed - so TMG is doing something stupid.

I feel bad ripping on the old company that did the IT support, but in other sites we have taken over from them have had some similar messed up setups causing the same kind of ridiculous issues which is why i am wanting to remove another of the servers they set up.

So my question is - Is it safe to remove TMG from the network, and if so would it be advisable to replace it with something else (IPCop or something similar possibly?) in addition to Watchdog that seems to be mandatory for educational sites.

Thanks in advance
