Installing TMG 2010 on new box, 2 NICs - found post that said to verify that internal NIC was top binding ( http://social.technet.microsoft.com/Forums/en/Forefrontedgegeneral/thread/9fcef70b-f930-44e7-908e-bbd951dba0cd ), it was #1 in the list - but it is physically NIC2 in the server (MB with 2 onboard NIC).

Install, stops and rolls back with "Setup Failed while Creating ForeFront TMG Storage"

My only choice was OK.

All Windows Updates are Installed

All Pre Req tests completed successfully from TMG software - and it launched the installer.

Not sure where to start looking.

Thanks

I'm currently using ISA2004 in a lab that requires authentication for all users.

If I perform a network capture I see that depending on the machine configuration I will use KERBEROS or NTLM.

So the request for www.google.com goes to the proxy server, the proxy server comes back with a 407.  In the header the following authentication types are listed in Proxy-Authenticate tags:

Negotiate, Kerberos, NTLM, Basic realm="fqdn.of.proxy.server"

For instance in IE if I specify my proxy by IP it uses NTLM, if I specify by its FQDN then it will use Kerberos.

Is it possible to configure these?  IE can I modify something so NTLM or Basic or Kerberos will never be a choice?  IE can I see it so the only suitable authentication mechanism is BASIC or KERBEROS?

Hi,

we have a Microsoft Sharepoint 2010 site deployed on Internet using Microsoft Forefront TMG.

In TMG Reports we found that, the website is taking a process time around 50-60 seconds for the time between 11PM- 5AM daily.

To lower the processing time in accessing the site on Internet, recently I have scheduled Content download Job of cache on TMG.

But I am receiving this Error message on Event viewer"While running the content download job MyWebsiteContent1, an unauthorized Web page was found: "

The SharePoint site is enable with claim based Authentication.

According to my understanding as mentioned in below link, it is mentioned in NOTE, content download job will not work fine for web sites which asks for Authentication.

http://msdn.microsoft.com/en-in/library/ff823923(v=vs.85).aspx

Please let me know if there is anyway to provide credentials in scheduling this job and download the website content to the cache?

Also please let me know if there is any possible way to check whether the content is downloaded to cache or not.

Any help is appreciated.

Thanks,

Harish.

Hello,

we need to set up a site to site vpn with a nat relationship to one of our partners.
They require that NAT IP address is the same as endpoint IP address, so they expect the natted IP to be our public IP.

PRIVATE (172.19.0.0/22) - TMG 2010 SP2 Rollup 3 - PUBLIC XYZ

The expect that PUBLIC XYZ is used as the natted IP address; of course PUBLIC XYZ is also the tunnel endpoint specified in the IPSec.

Is this configuration possible ? How to do it ? We tried in Networ Rules to add a NAT relationship from Internal to Partner, but the NAT address selection does not allow to specify our public IP address (PUBLIC XYZ) ; if we try the "Use multiple IP addresses" the list is empty and if we try "Add IP" and type in PUBLIC XYZ it says "The specified IP address does not belong to destination network". Do you still want to add this IP address to the list of NAT addresses" ?
if we say "yes" (default is "no"), ok, finish and then try to open the network rule back to check the setting, it reverted back to "Use the specified IP address" with a blank value.

Hi all, I am very new to TMG and inherited a single TMG server that only has one NIC that has rules configured for Exchange services (OWA, OA, EAS). The rules seem to be setup and running correctly, however accessing OWA from an external network, is painfully slow. If I restart the TMG services OWA appears to work fine again for awhile but will slowly begin to crawl over time.

Again everything appears to be published correctly because once OWA comes up it is accessible and there are no certificate warnings, etc. however I am not sure where else to begin looking.

Any help is appreciated!

I have a strange and intermittent problem. I use Forefront TMG 2010 to publish Exchange 2010 (using separate rules for webmail, Active Sync, and Outlook anywhere + autodiscover. Normally this works correctly but we have instances where traffic is being dropped by TMG, but at the very same time, traffic from other networks into the same TMG are working correctly.

So I get a complaint from one user located somewhere that whenever he tries to reach the webmail URL he gets " internet explorer cannot display the page", whilst at the very same time, I am able to access OWA from my home, when using my phone and even from the office. Now if troubleshooting the issue, and using TMG's log I can see that from the IP address at which the complaining users is at, packets are being dropped with messages similar to :

0x80074e21 FWX_E_ABORTIVE_SHUTDOWN

Whilst at the very same time, people from other locations have no problems whatsoever to reach the very same published website. The only fix is to restart the Microsoft Forefront firewall, after the recycle of this service connectivity is restored for the complaining user.

hi friends

i searched internet but didn't find an answer for my q.

i have a LAN with a tmg server. my clients ( are TMGC clients) need t establish a vpn connection with external vpn servers.

i read in TMG admin companion book that TMGC clients ( tmg client software installed) can not establish vpn connections because TMG doesn't support GRE protocol.

is it true ?

what a bout other vpn protocols like l2tp\ipsec ?  sstp ?

thanks in advance

Hello all.

In my environment i have TMG as firewall and proxy between internal and external networks.

So at my sbs server i have a new website wich requires port 80 but have a webservice at port 8732 and 8733.

So at TMG i created a web listener for this new website only with http. I have also created an access rule for TCP ports 8732 and 8733 for inbound and outbound access from everywhere to host.

My external access is using a dyndns name.

My problema is that when i connect from the outside the website opens but everything that requests the webservice doesn't work.

Is anything more that i have to do?

hi friends. i looked at some documents on internet about TMGC application settings but finally i didn't understand what is 

difference between Disable and DisableEx keys in TMGC Application settings ? bot disable a specific application (e.g. firefox).

i Guess via disable key we can for example set * to disable all applications communications with internet & here with DisableEx key we define exception ( e.g. IE be able to connect ).

is my understanding true ? or the fact is different ?

thanks in advance

We have just setup a VPN connection to a customer's site so we can RDP to a couple of their servers on their domain. For some reason, after I connect to their VPN, I cannot connect to their server via RDP. It just times out and says "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." I can ping their server IP address once the VPN is established, just not connect via RDP.

I have discovered that if I disable the Forefront TMG Client on my PC, I can RDP to the server without any problems.

Why do I need to disable the client to do this? I already have a rule on the TMG 2010 server for outbound connections to RDP (3389) and this works well for a number of other clients we RDP to (with the TMG Client enabled). I don't understand why this one is different.

Any help much appreciated.
