Hi guys,
I have a need to monitor VPN clients where I have TMG 2010 as my VPN server.
I just want to know from where clients are initiated their vpns.I mean their vlaid IPs not which TMG gives them.
Is there any third party software to do this?
Thanks
The recurring daily report for all users is working fine but the user activity report does not work as the report is empty
so pls advise how can I check this issue

Dear Mates,
We have published Exchange 2013 via TMG 2010.
Users cannot logoff OWA with message "to finish signing out,please close all open windows"
Even when closing the browser the session is not terminating.
Thanks,
Hello,
Hello,
I attach the image so it is easier to understand.
Basically, as the drawing says, I am trying to reach DC1 from TMG2, but I am unable. To achieve it I just added a route (red-coloured in the image) to the TMG2 machine, but the log keeps telling me "Packet dropped because the ip is unreachable."
I really don't know why it is that the machine can't get to DC1, the firewall is off.
Also, TMG1 allows all the icmp traffic from the Perimeter to the LAN.
I have a question: TMG2 sees 192.168.2.0/24 as external, I don't have a definition for such network in the TMG2 machine. There is the NAT relation between the Perimeter network and the External , and I am wondering if this is what is causing all the issue.
I edit the post to ask another question:
I have a route relationship between the LAN and the Perimeter network in TMG1, I wonder if that should be a NAT relationship between those two networks.
Thanks in advance!

I have TMG 2010 set up in a 3 Legged approach: External, Perimeter (DMZ) and Internal. I have a webserver in the DMZ which hosts multiple websites, one of which requires an SSL connection. I have set up an SSL listener and installed the certificate for the domain in the Personal storage on the Local Machine (the TMG) and published a website site rule which uses the SSL Listener.
However, when trying to access the site over HTTPS I get the error:
"Error Code: 500 Internal Server Error. The certificate chain was issued by an authority that is not trusted. (-2146893019)"
The certificate is from a valid certificate authority (Global Sign) and is confirmed in my Internet Browser.
When testing the rule from the TMG I get this error:
"Time reported by the Microsoft Forefront TMG Firewall Service: 0.010 seconds
Testing https://appstore.mydomain.com:443/
Category: Destination server certificate error
Error details: 0x80090325 - The certificate chain was issued by an authority that is not trusted."
I read that this is caused that when the certificate is not in the Trusted Root. I have copied the certificate from Personal into Trusted Root and the same problem persists.
Hi all,
I have an installation of Forefront TMG 2010 with Websense Web Filter Plug-In. The task I am supposed to do is to disable redirecting requests to Websense for specific source networks. It is impossible to do it from Websense Server, due to license limitations.
I know there's a way to ignore some source users from isa_ignore.txt but I should filter this basing on source IP addresses. Please help me solving this issue.
Kind Regards,
Good Day
We are blocking facebook.com in our company using forefront tmg 2010.
the problem is now, if a site has a facebook plugin (for example i like button) which is blocked, the tmg message is overlay over other text.
how can we Change this behaviour?
Thanks
Hi,
SSL 3.0 vulnerability was founded.
Vulnerability in SSL 3.0 Could Allow Information Disclosure
https://technet.microsoft.com/en-us/library/security/3009008
I’m anxious about this vulnerability.
And I’ll take action to this problem.
I’m using “Forefront Threat Management Gateway (TMG) 2010”.
Is it OK if the TMG SSL3.0 be disabling?
Thanks

Network A <-> Network B <-> Network C
Network A has a VPN connection to Network B via TMG 2010
Network B has a VPN connection to Network C via TMG 2010
Network C is a network in the Azure Cloud
Network A: 192.168.1.0 - 192.168.1.255
Network B: 192.168.2.0 - 192.168.2.255
Network C: 192.168.3.0 - 192.168.3.255
Requirement: Allow access from network A to network C via existing VPN
Issue: TMG between Network B & C denies traffic because of the following issue:
"A non-SYN packet was dropped because it was sent by a source that does not have an established connection with the Forefront TMG computer"
A route rule exists on both TMG's. But the route rule on the TMG between network B &C keeps NATing traffic from network A with the external interface of the TMG firewall.
Both TMG's have been configured to use a route rule and not a NAT rule.
FW rules are in place on both TMG's to allow a non standard HTTP protocol (I have created a new protocol and unbound HTTP from the Web Proxy Filter).
Any help is appreciated to get this route rule to work.
Thanks!
Hello,
I have a TMG machine between my LAN and my DMZ, and another TMG server facing internet, between the DMZ and the DSL router.
I am not an expert in TMG and I really don't know if the rule between the LAN and the DMZ must beNAT or ROUTE.
Thanks in advance !

Hi I need to create a TMG rule to allow connection using TLS and HTTPS to all Lync online URL's:
*.microsoftonline.com
*.microsoftonline-p.com
*.onmicrosoft.com
officecdn.microsoft.com
*.sharepoint.com
*.outlook.com
*.lync.com
evsecure-ocsp.verisign.com
evsecure-aia.verisign.com
evsecure-crl.verisign.com
sa.symcb.com
I have already configure a rule for all necessary TCP and UDP ports outbound but would like to include the above URL's in TMG also. Can anyone tell me the best way to configure this?

Hey..
I have almost succesfully published and allowed RTP and SIP through TMG, we can make calls from the VOIP phone, but we are unable to receive calls.
When we call the VOIP phone then it sends UDP traffic ranging from 10.000 to 50.000 and that UDP traffic gets stopped by the TMG. We dont have an internal BPX so we cant publish in that range because we have several phones. What can i do? :)
Hi Team,
i had task to compile detail ISA firewall Log. I convert msde into txt file and then filter rule for VPN only.
but, at that rule show there are any log that not show user name.
what the mean of this weird log? is that user activity or just system logging?
thanks

When I look up alternatives to TMG many other answers say something like "Don't worry about it. TMG 2010 is under support until 2020."
Well, we don't have TMG and can't buy it since it is off the market. Can it still be legitimately purchased through any resellers?
We need a reverse proxy that specifically supports SSL-Bridging so that device certificate authentication is not broken when the connection passes through the proxy.
Which reverse proxies that are currently on the market are known to work successfully with System Center Config Manager Internet-Based Client Management and also with other Microsoft products such as Lync 2010 and RD Gateway 2012 R2?
Do any Cisco ASA or ACE models support the required functionality for machine certificate authentication?
We have ISA 2006 licenses available, but I would hate to roll that out and then have to replace it in only 2 years rather than using something that can stay in place long term. Maybe we could use ISA 2006 temporarily as a stopgap if the next version released of Windows Server Web Application Proxy would meet the requirements and can be deployed in production before ISA 2006 is completely EOL.
I hate that Microsoft keeps discontinuing all the related products to this before they have their replacements ready.
I have an odd problem that surfaces every once in a while and that bugs me. When I try to remote into my TMG box, I get the dreaded "The connection cannot be completed because the remote computer that was reached is not the one you specified" error. The normal fix for this problem (ipconfig/flushdns) does nothing and I can't RDP via ip address.
I have no idea what causes this, either. One day it is working fine and the next, it tanks. Has anyone seen this before and do you know how to fix it? I currently can't remote into the box at all.
Hi,
I'm new to microsoft products, so hopefully I can get my point across meaningfully.
I'm trying to connect to a site internally through forefront/tmg and recieve this message:
Error Code: 403 Forbidden. The server denied the specified Uniform Resource Locator (URL). Contact the server administrator. (12202)
I assume I'm getting to the site, but appears to be some sort of rights issue as to why I can't see the content.
Any ideas how to troubleshoot this and steps to take?

Hi,
I have a question?
Can TMG can be installed in a Vitual machine irrespective of different vendors? I mean to ask whether it can be installed in Hyper - V, VMware, Xen machines?
How effective the TMG behaves when it would be installed in Virtual servers?

Hello,
After removing TMG 2010 from a Windows 2008 R2 server, the following TMG Packet filter was left behind and the "uninstall" option is greyed out.
How can I uninstall this? Any ideas greatly appreciated... (see image below)...
