Dear Expert,
I installed TMG 2010
and after that I found that all clients who run outlook to connect to their personal emails dont receive any emails and show to them error messages
how can i fix this problems?
Hi, I need to know if it is possible to have forefront TMG redirect outbound web traffic to a an alternate IP for a specific host name. Our client sent us software to test with a hostname, but wants it to hit their test servers at a different IP address. They thought just editing the host file would work, but forefront is still doing a DNS query when we run the software.
I saw the ISA toolkit from Redline, and it appears to add advanced routing which would do exactly what we need, but it doesn't run on 2008R2/TMG 2010. Is there any other way to set this up? Or any software comparable to the ISA toolkit that is compatible
with TMG? Thanks.
Hi All,
I am looking for a way to view a bandwidth usage of clients (established sessions) over a TMG VPN
is there any way to view (no necessarily monitor) this in TMG or any tool, plugin ?
Thanx

Hello can anyone give some insight as to how this can be accomplished? Here's some setup info...
ISA 2006 Front End Firewall
DMZ - Web Proxy's - DMZ
ISA 2004 Back End Firewall
The front end firewall obviously has no connection to the domain, while the back end firewall does. I have a website that is published on the Front End Firewall, which then forwards the requests to my web proxy, which then forwards the request to the back end firewall, and then on to the actual web application. I need to add security to this setup by use of SSL Authentication. Any suggestions?
Thanks,
We have an ISA 2006 build 5.0.5712 operating as our web proxy. We have WPAD configured both in DNS and in DHCP to point to this ISA server. There are two sites (rentsentinel.com and epmsonline.com) which when we use the 'Automatically detect settings' option in IE8, it either gives red X'es in part of the homepage (rentsentinel), or doesn't show the page at all (epms). If we manually specify the proxy settings for this same server, it works fine. It would also appear that one can browse fine on random sites, but once we attempt to browse to once of these two sites that further browsing, even to sites which just worked fine, no longer works.
I'm looking for help on getting these sites working correctly with automatic detection. Thanks!
Edit: If I manually specify the http://wpad/wpad.dat file in the config field, no change in behavior. But if I use that same entry in Firefox, both websites render fine.
Hello,
I am having an issue with getting my TMG (EE) server to allow PING from a client on the same subnet. This is a lab enviornment, but the same thing is happening my production enviornment. I am attempting to allow PINGs from CLIENT01 to get to TMG01 and allow TMG01 to respond back to CLIENT01. When I ping the TMG server, I get no reply on the client. I see this traffic on the TMG live log and it's is being DENIED by the default rule. See attached image. Am I missing something here? I've even tried creating an access rule and no luck.
Details:
-Single NIC on TMG01
-Only Firewall Policy is the Default Deny policy
-CLIENT01 has been added to Remote Management Computers computer set
-Verified the System Policy Editor has ICMP (Ping) enabled and has Remote Management Computers in the FROM tab
-System Policy Rule:
Name: Allow ICMP (PING) requests from selected computers to Forefront TMG
Action: Allow
Protocols: PING
From/Listener: Enterprise Remote Management Computers & Remote Management Computers
To: Local Host
Condition: All Users
Policy: System
We have TMG Essential Business Server. The TMG management console fails to open:
Refresh Fail Error. Error 0x8009005, Bad Data.
We are not running VPN so this solution does not apply http://support.microsoft.com/kb/2006046?wa=wsignin1.0 (There is no VPN heading in ADSIEdit console)
Has anyone found a solution this apart from re-installing see http://social.technet.microsoft.com/Forums/en-US/Forefrontedgesetup/thread/d6696c0d-d279-4723-8d1b-a09259a53b2f.
The problem occured shortly after adding some firewall changes.
Is it possible to edit firewall policy settings from the console to see if it will clear the error ?
I have Main office and branch linked with 2 TMG 2010 (+ all SP's and all rollups) over PPTP site-to site.
Sometimes some clients can't access to main office sourses with 0xc0040014 FWX_E_FEW_SPOOFING_PACKET_DROPPED on branch's TMG; internet sill works.
Everytime diffrent client, but no more then 1 at once.
There are 2 providers on branch office with ISP.
I have TMG deployed at a customer for publishing Exchange 2010. I am having trouble with the Connectivity Verifiers. I created 3 Server Farms (one for OWA, one for ActiveSync and one for RPC) and each server farm was set to verify the specific virtual directory
in question.These farms are set to go to the actual servers themselves and not through the load balancer.
OWA: https://*/owa/
ActiveSync: https://*/Microsoft-Server-ActiveSync/
RPC: https://*/rpc/
At first, it seemed to work, but now those do not work at all, even though I can manually browse to those virtual directories from the TMG server. However, when I change the Connectivity verifiers to either the Ping method or Port method (443), the verifiers work. Any ideas on why the other verifiers are not working?

Hi All, I am trying to configure an IPSec site-to-site VPN connection between our Essential Business Server 2008 Security Server, running TMG Medium Business Edition (MBE) and a Cyberoam CR35wi located at a remote site. While the process should be very simple, I am simply not having any luck getting it to play nice.
Both TMG and CR35wi have identical configuration for IPSec connection; Phase 1, EA = 3DES, AA = SHA1, DH Group = 2 (1024), Key Life 28800 - Phase 2, EA = 3DES, AA = SHA1, PFS Group (DH Group) = 2 (1024), Key Life = 3600. Both utilise the same Preshared Key.
The CR35wi reports connection issues, e.g.: "EST-P1: Peer did not accept any proposal sent.", "EST-P2: Max number of retransmission 2 reached. No response to first quick mode message. Perhaps peer likes no proposal."
While TMG shows successful connection in log:
And in TMG Sessions:
Any attempts at pinging or accessing resources in remote networks are met with failure, so the connection doesn't appear to be valid.
While troubleshooting the problem using "Troubleshooting VPN over IPSec" (http://technet.microsoft.com/en-us/library/bb794765.aspx) I found that policyagent service had been disabled on the TMG server. Now I installed the EBS2008 deployment myself and know that I didn't disable that service, so I'm now in doubt as to whether IPSec is functioning properly on the EBS Security Server/TMG. As EBS2008 has been discontinued, documentation specific to this platform is difficult to come by.
I'd appreciate it if anyone could assist with verifying that IPSec VPN support is indeed fully functional in TMG MBE as deployed with EBS2008. Is there a simple way to test this?
Regards,
Byron.

We are deploying TMG as our front end firewall to replace ISA 2006 and have been receiving "A non-SYN packet was dropped because it was sent by a source that does not have and extablished connection with the Forefront TMG Server". We only see the error when trying to access a web hosted application over a Citrix connection and it doesn't occur in ISA. What the clients see is a Citrix generated proxy authentication dialog which does not accept the credentials when they are entered and only pops the dialog back up again. The application never starts.
I have authentication enabled in the main web access rule, and if I turn it off, (change All Authenticated Users to All Users in the Users tab of the web access rule), I am able to connect. All other internal and external traffic seems to be fine, just this one application. Any idea what might be causing the error, or how it is connected to authentication.
Our current ISA 2006 box also requires authentication (require all users to authenticate is checked in the Internal network properties), and does not have any problems connecting.

I need some help with WPAD. I am using WPAD now and need to add a function for ipv6. I know that the ipv4 is FindProxyForUrl (url, host) and ipv6 is FindProxyForURLEx. I need to know how to add this function. I also need to know what I need to know what else goes in the WPAD file.
Thanks for any help you can give.

Hi,
when publishing a port forwarding (non-web server) rule for an unknown (by TMG) protocol - TCP/1521 - our windows 2008 R2 box halts ("hardware malfunction" BSOD with no error messages "the system has halted"). We've updated firmware on the box, updated all the drivers, all the firmware, swapped out the memory, reseated HDDs & RAID card. Windows is updated to the max, and rollup 2 applied to SP2 of TMG 2010, version 540.
The "halting" only occurs when the network interface receives a packet for this rule. The box is otherwise completely stable, which is why I'm leaning towards aTMG + Driver rather than hardware error. The tin is a Cisco C200 with LSI megaraid, Intel networking. 2008 R2 installed directly to tin, no vmware.
Anyone experiencing similar problems, I'd be grateful for any advice :)
Thanks in advance,
Sam.
Good morning,
Last night I patched our TMG server and rebooted. Since then external people have not been able to access any ot our https sites including OWA and has the error message - "status: 64 The specified network name is no longer available.".
This morning I checked the patches and noticed that KB2574819 was to do with DTLS. I removed this and rebooted the server - Hey Presto everything worked.
Can anyone explain whay this patch should stop access to https sites - the boss wants to know!
Thanks
