Hi,
We have Branch Office 14 to 15 nodes and users are connected through VPN connection for accessing intranet which are placed at our head office. but they have full internet access now i want to restrict them to access full internet so i decided to place TMG server at branch office.
my plan is it to dial vpn on TMG machine.
vpn allows users to access intranet and tmg controls internet. do u think is it worth able.

Hi,
I have a forefront TMG array consists of 2 servers, currently publishing Lync 2013 services. I wanted to publish Exchange 2007 (Exchange 2013 in future) also using the same array.

I want to host a iis site which is running in my private network behind the ISA 2010. Can anybody help me with the process to configure ISA 2010 so that the IIS page is accessible through public IP which is hosted in my private network..
I want to forward the http request coming to the public ip to my private IIS Page.
We currently are trying to publish Server 2012 r2 rdweb through TMG. We get to the point of launching an app, and get the message stating that your computer cannot connect to the remote computer, because the remote desktop gateway is temporarily unavailable. The solution works fine internally, so we suspect it has something to do with TMG. We get 3 denials when logging traffic:
1)

We also have a 2008 R2 server published (using different URL's, Listerners, rules, etc...) which works perfectly fine.
I need to create a protocol definition for HTTP which doesn't include the Web Proxy Filter to workaround a problem as specified in this blog:
"To allow the nonstandard HTTP traffic, you need to create two access rules:
The new allow rule must come before your original rule that allows HTTP traffic from <source> to the External network in the ordered list of policy rules, and the new deny rule should be placed immediately after the new allow rule."
I created a new protocol, choosing TCP port 80 outbound and made sure not to add the HTTP Proxy Filter. I must be doing something wrong because the access rule that I created (similar to the Allow rule above) using the custom protocol is skipped over when the source client tries to access the destination URL specified in the rules. It goes right to the Deny rule (similar to the one mentioned above).
The difference is that the Deny rule (which has the Web Proxy Filter) shows up under the Web Access Policy, whereas the Allow rule (with no Web Proxy Filter) only shows under the Firewall Policy. I believe this is a clue that I didn't create the protocol correctly, but I can't see any other way to do it.
Thanks in advance for any help on this. By the way, the reason I need to do this is because the Windows 10 1511 Update will not sync with a WSUS that is behind TMG. It seemed to work for another person affected. See my post for that issue:
In our sites we have a software program called Milestone, this program is for security camera's. When we try to make connection with the camera's we get this error in our forefront and the stream for the camera's don't go open:

I already disabled HTTP compresion, malware inspection, web proxy and I allowed alle outbound traffic between the internal/external and external/internal network. Also I inspected the traffic with wireshark and network monitor but can't see anything in it. I'm searching for 5 days and I can't find a solution, because this error doesn't tell anything.
How can I solve this?
Hello All,
We just recently introduced Exchange 2013 into a mixed Exchange 2010/2007 environment with TMG 2010. We had no issues with TMG and any Exchange 2010/2007 protocol.
We installed Exchange 2013, created new TMG rules as per the MS Technet articles and pointed eveyrthing on the TMG server to the Exchange 2013 CAS roles via a TMG web farm.
Everything is working correctly on all Exchange 2013/2010/2007 servers *except* for Outlook Anywhere for the test mailbox that we have on the Exchage 2013 server. We cannot successfully configure a OA session the the 2013 mailbox - it keeps prompting for credentials. When we direct the Outlook client to go directly to an Exchange 2013 server via a hosts file, OA works without issue so it appears to be something related to TMG.
So we've spent a bunch of time checking settings and trying different combinations of settings on both the TMG policy for OA and the Exchange 2013 CAS roles without any luck - we cant seem to authenticate the OA client and establish a session.
Interestingly enough if an Exchange 2010 user with the correct rights tries to open the Exchange 2013 test mailbox, they will eventually be able to open it but only after a delay of a minute or two.
Any ideas?
Does anyone have a set of working TMG and Exchange 2013 settings for a mixed environment that they can share here ?
Thanks
Thanks

Hope someone has been able to resolve this issue.
We are using TMG in a Single NIC configuration as a reverse proxy for publishing internal websites externally. In our environment, we have a hardware load balancer in front of the TMG, which redirects SSL traffic from port 443 to port 5443. On the TMG, we have a weblistener which listens for SSL traffic on 5443 and then directs it internally.
The issue that we are having is that, when the user views the page, the initial request to the login page works fine, but when the login page redirects to another page, the url is returned withhttps://url:5443 instead of https://url.
It seems that because the TMG sees the traffic coming in on port 5443, the traffic, it sends it back on the port but changes the url even though the url coming in does not have the port number in the first place.
Tearing my hair out over this as the network guys says they don't make any changes to url when it gets sent to the TMG and logs seems to indicate it.

Hi,
We connect to our SharePoint 2013 farm through TMG server. Everything works perfect with Office 2013
Since Office 2016 our users having problems when open and save documents through TMG.
For example:
When you click on a Word document on SharePoint, Word open but only in read only mode. Normally you should see a yellow information bar with a ‘Edit document’ button.
I can go to the ‘view’ tab-> ‘Edit document’ but the document stay in read only mode but I can edit the document. When I save the document, Word trying to connect to the SharePoint document library again but that fails. Instead Word open the local c:\drive.
In fiddler I see the error “Error code: 403 Forbidden. The server denied the specified uniform locator (URL)” when Word trying to connect to the document library on SharePoint.
I did a little research and found that that the ‘Modern authentication’ in Office 2016 is set as standard.
http://techblurt.com/2015/09/29/office-2016-authentication-against-legacy-sharepoint-online-bpos/
When I set the “EnableADAL =0” then everything works perfect but that is not an option because we don't have control on all the clients with Office 2016 installed.
My question: Is there a workarounf or hotfix for TMG.
Regards,
Johan

I have a Galaxy Note4 running Android 5.1.1. When I try to access my company's email via a browser, I continuously get the following error:
"You could not be logged on to Forefront TMG. Make sure that your domain name, <g class="gr_ gr_104 gr-alert gr_spell undefined ContextualSpelling ins-del" data-gr-id="104" id="104">user name</g>, and password are correct, and then try again."
I have double-checked my login credentials many times but still get the error.
Looking through Microsoft support, it said the fix was to install Front TMG service pack 2. How do I install that on an Android device?
Thank you.
