Has anyone tried successfully installing Forefront TMG 2010 on Windows Server 2012?
I tried but failed, it complained about unable to add roles and features.

Microsoft updates break Outlook Anywhere: "An HTTP 403 error was received because ISA Server denied the specified URL"
We ran all the Microsoft monthly updates yesterday on all our servers (I think this included an SP rollup). Since then, our Outlook Anywhere has stopped working. I suspect that it has something to do with the TMG 2010 publishing rule for Outlook Anywhere.
I tested the external HTTPS over RPC connection and the test failed with the following error:
| Testing HTTP Authentication Methods for URL https://external.address.org/rpc/rpcproxy.dll?internalservername.domain.org:6002. | |||||
| The HTTP authentication test failed. | |||||

policy enforcment if content type is derived from requested URL path
hi friends
i am new to TMG and i am trying hard to Learn it.
in TMG Administrators Companion book, in page 253, under the title "Policy Enforcement in Certain Scenarios" we read :
"However, in certain scenarios, the content type can be derived from the requested URL path, and then this information will be used to match the policy. No renegotiation will be performed with the Web server."
i don't understand this sentences. can anyone describe me in simple words and with a simple examples ?
thanks very much in advance

TMG 2010 - Sporadic 10060 Timeout
I have been having some issues with one SharePoint site published through TMG that keeps timing out randomly.
A couple of times per day my users get a 408 error message from the webb browser saying that the connection has timed out. At the same time the TMG logs timeout errors as well:
"10060 A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. "
The network topology looks something like this.
Both internal and external users access the site through TMG and are experiencing the same problems, so the firewall isn´t the one causing the problems.
Lately we have been testing with two users who access the site directly(not going throught the TMG) and they haven´t had any timeout problems, this makes me believe that the problem isn´t with the SharePoint server itself.
I have been runing a Wirshare capture on the SharePoint server during one of the timeout sessions.
In the first image we see that the TMG(10.150.8.9) sends a GET / request to the SharePoint server at 15:46:40 from port 61293. Now this is interesting since no data has been sent from port 61293 in the last 9 minutes as you can see in the second image.
Same thing in 15:46:48 form port 61297.
Hasn´t that port/session timed out? Isn´t a three-way handshake required then?
I´m starting to believe that there is something fishy with the TCP communication between the TMG and the SharePoint server.
I should mention that we have other websites published throught TMG that work flawlessly.
Any help will be greatly appreciated! :)
Best Regards

Trying to publish security gateway appliance in DMZ
I am trying to publish a PCoIP Security Gateway from a DMZ using the only public IP address we have available.
We have TMG 2010 appliance with 5 NICs:
1 Internal - 10.100.10.254/24
1 External - 204.9.159.XXX/29
1 DMZ - 172.16.0.1/24
2 Unused
On one of our ESXi hosts I added a new NIC and created a new vSwitch. I added the security gateway appliance to the vSwitch and connected this new NIC to the DMZ NIC on our TMG appliance.
I need to publish out this security gateway on ports TCP 443 and 4172 and UDP 4172. We are already hosting websites on the public IP address assigned to the External NIC so I assume I need to use the one remaining public IP address I have to publish out this security gateway.
I have a few questions to try and figure out the best route for accomplishing this:
1 - Do I need to assign the DMZ NIC the remaining public IP but give the security gateway a private IP and use NAT? Or do I dual-home the External NIC with the remaining public IP address?
2 - Do I use access rules or publish rules to give the External network access to the DMZ network?
3 - Is there an easier way to accomplish this that I'm unaware of?

Log specific http requests
Hi. Is possible to log specific http requests.
For example if people visit specific web pages (urls) and even submit some text data to them?
We do not want to deny that urls, but monitor what people are sending.
I imply http and not https...

ISA 2004 http to https redirect on OWA publishing rule
I am in the middle of an Exchange 2003 to Exchange 2010 migration. This is an interim migration and the team wanted to use the current firewall to continue to protect the Exchange 2010 OWA site. I've figured out the paths to get everything to work when connecting to https://mail.mydomain.com from an external network. I've configured the http redirect on the Exchange 2010 CAS so when I connect from an internal network tohttp://mail.mydomain.com I am automatically redirected tohttps://mail.mydomain.com/owa. What I cannot get to work is connecting tohttp://mail.mydomain.com from an external network. I just get a http 403 - forbidden. This page must be viewed over a secure channel. The publishing rule is set to allow connections over port 80, so is the web listener and the Bridging tab has port 80 enabled. If I open a web browser on the ISA server I can connect to http:/mail.mydomain.com and be redirected tohttps://mail.mydomain.com/owa. All I need ISA to do is to redirect the initial request to https. I've tried Link Translation, but it appears to have no effect. I've seen a lot of posts stating that the http redirect never worked in ISA 2004 and I've seen http redirect with link translation "works like a charm."
When I monitor the connection, the http connection from an external network is blocked by my owa publishing rule. Can anyone say with some authority that http to https redirection works on ISA Server 2004? If so, can you point me to step by step instructions for ISA Server configuration to allow the http to https redirection?
TIA

TMG unable to show IP address of user.
Hello,
We are using Forefront TMG as an internal firewall in our office. We have a internal application in our organization when ever a user from the organization access the application from his computer the user IP address and Username is being logged in the application server.
But when user access it from TMG, only TMG WAN network card IP address is shown in the application server.
The IP address and username is required to be logged in the server.

Publish share calendar
Hi Everyone
I have referred to the following post on how to publish public calendar sharing via TMG.
I made a copy of our existing TMG OWA Publish rule and created a new rule to match the following configurations
- On your Firewall Policy click Publish Website.
- Use the same details as you would for the OWA Publish rule and use the same Listener. (Make sure require authentication on the listener isn't checked)
- For the path of the new rule use /owa/calendar/*
- Under Authentication Delegation select "No delegation, but client may authenticate directly"
- Under Users select "All Users"
- new rule is a higher priority than the one publishing OWA.
Saved the TMG setting.
When I try to access the published calendar link it redirects me back to the OWA Forms-Based Authentication Page.
Any suggestions/workarounds in regards to this issue.
Thanks

TMG: SSL traffic fails. Destination: External (255.255.255.255:8080)
Hi,
We are in the process of configuring TMG 2010. From a web client, all is good as far as HTTP traffic goes. We get the page returned without issue. The problem occurres when we try and browse to SSL (443) pages.
In the logs, we see the line:
Destination: External (255.255.255.255:8080)
But what we don't understand is where is this "255.255.255.255" address coming from. On are current ISA 2006 server, we see Destination: External (173.194.41.96:443).
On our external firewall, sitting between the TMG server and the big bad world, we don't see anything coming from TMG.
I'm sure it is something really simple, but we just can't figure it out.
Below is a screen shot of the issue.
Any help would be greatly apreciated.
Thanks

Port-forward to External IP that is connected to same router/switch.
I'm trying to access a client machine via VNC on an external IP address. The client machine it's on the same building as our main network but on a separate network behind a TMG 2010. The problem I have is that our main network and this client machine once they go past the firewall (separate TMG 2010 for both networks) they connect to the same switch to get to the internet.
I have set up the port forward on the TMG to access the VNC Client and it works fine if you connect from an external network on the internet. The problem is if I try to connect from my internal network it doesn't work. So, I think because both networks connect to the same switch, traffic never goes out to the internet.
Below is a graphical diagram that explains a bit more about the network layout.
For example I try to access the VNC on 10.10.10.1:5902 and it doesn't work. However if I just try to use IP address only then it connects fine.
The reason we need this is that we need customers to be able to access a test machine from the internet and for security reason is on a separate network.
Any advise would be appreciated.
Thanks

TMG ISP redundancy problem. I can not use websites which I public on ISP1 IP from internal clients if the redundancy is enabled...
Hi,
situation for example but my looks similar as this:
ISP1:80.80.80.80
ISP2:90.90.90.90
Internal:10.10.10.1
Client:10.10.10.2
If I configure IPS redundancy to load balaced mode ( I used manual from isaserver.org and advices from ms technet ) I can not ping from client IP 10.10.10.2 neither ISP1 nor ISP2 IP adresess and I can not use websites ( owa onhttps://gate.company.com/owa ) from internal clients. I can ping the both of IP from TMG and I able to acces the websites as well, but not from the clients. If I do not use ISP redundancy everything works fine. I think
the problem is with the route or NAT configuration. I tried to set my IP ( ISP1 there is the website ) to dedicate servers for ISP1 but with no effect. From internet everything works fine to. Problem is only from internal sites with ISP redundancy enabled.
Thanks for advice

Missing HttpOnly Flag From Cookie
We have recently configured TMG to offload the FBA for OWA. When we have done this and run a penetration test we fail with the results below:
Missing HttpOnly Flag From Cookie
HttpOnly is an additional flag included in a Set-Cookie HTTP response header. If supported by the browser, using the HttpOnly flag when generating a cookie helps mitigate the risk of client side script accessing the
protected cookie. If a browser that supports HttpOnly detects a cookie containing the HttpOnly flag, and client side script code attempts to read the cookie, the browser returns an empty string as the result. This causes the attack to fail by preventing the
malicious (usually XSS) code from sending the data to an attacker's website.
Missing Secure Flag From SSL Cookie
The Secure attribute tells the browser to only send the cookie if the request is being sent over a secure channel such as HTTPS. This will help protect the cookie from being passed over unencrypted requests. If the
application can be accessed over both HTTP and HTTPS, then there is the potential that the cookie can be sent in clear text.
I have loooked for walkthroughs for this and can’t see anyting definitive.
Can anyone point me in the right direction please?

Web protection without HTTP protection license
Hi,
We've TMG 2010 and our trial license for Web protection (HTTP protection) has been expired. Our team can't get approval for this license, so we've to live without it.
Well, we'd like to setup TMG rule and block:

- network traffic for gtalk and skype services, online or standalone desktop version.
Can you please advise how to do this?
Thnx!
