hi all
i am using utm.but now i want to use TMG as proxy server for web filtraing ,i want website filtering and application blocking now my query is this
what i need to purchase to achieve this and if i dont take tmg webfiltring subscription then is it possible for me to do website blocking .
kindly provide me the solution it will be realy helpful if some one can provide me diagram
I have the following setup. 2x server 2008 servers (server 1 and 2 running TMG 2010 Stand alone array.
I have created one array and joined server 1 and 2 to the array.
I enabled NLB. I created a DNS entry on our DNS server and gave it the name "VIP"... I gave the primary virtual IP
in the NLB TAB on server 3 the same IP as "VIP"...
However I can ping VIP on my TMG servers but I cannot ping them from other servers such as my Exchange servers and client computers.
Any help?
Thanks,
I understand that there are a few requirements in order to publish SharePoint 2010 securely through TMG 2010.
some of the requirements that I managed to find are
SSL secured connections with clients
External Listerner
Select certificate
HTML form authentication with Windows (Active Directory)
No SSO(Single Sign-on).
Can I use do without No SSO ?
What other method can I use if I cannot use NO SSO ?
I have a problem that is causing much impact on the company. I have a server with TMG 2010 (SP2) + Windows Server 2008 R2.
I enabled the feature in TMG VPN client.
The VPN (RRAS specifically) is very unstable, failing to accept any new VPN client connection 5 to 10 times a week.
When this occurs, people already connected continue working normally, but those who try to make a new connection fail, the event is 20209.
Some situations I noticed when the problem occurs:
* The RRAS is "unmanageable", if I try to disconnect a user right-clicking on it and chosing disconnect , nothing happens, the user remains connected.
* If I try to restart the RRAS service it hangs on "stopping".
* The only way I can make everything work again is by restarting the server, then, all users can connect to the VPN again for another few hours or days.
Thanks to all who can help.

Hi!
I'm having an issue with VoIP calls via TMG 2010 PPTP VPN. I have internal IP PBX and I want that I could register softphone to IP PBX through TMG VPN and make calls. At the moment softphone can register to IP PBX, I can make calls from internal phone to softphone though TMG VPN and from softphone to internal phones, but on internal phone I can't hear anything when I'm talking on softphone, but if i'm talking on internal phone I can hear on softphone. Where is the problem? Any ideas?
Rules looks like that:
1. Protocol RTP from ( VPN Clients ) --> to (IP PBX);
2. Protocol RTP from ( VPN Clients, IP PBX ) --> to (VPN Clients);
3. Protocol SIP from ( VPN Clients, IP PBX ) --> to (VPN Clients, IP PBX);

We have a server with three network interface teams, which we want to use as part of a project to provide "internet cafe" style BYOD wireless access to the Internet. The idea is that traffic will be routed from the "internal" team to the "external" team and the other team will only be used for authentication with our main network's Active Directory.
The configuration of the three teams is as follows:
Internet Cafe Team: IP address 10.128.10.2, subnet mask 255.192.0.0, default gateway blank, DNS server 10.128.10.2
College Team: IP address 172.16.32.6, subnet mask 255.255.0.0, default gateway blank, DNS servers 172.16.178.4 and 172.16.178.2 (the domain controllers)
Fibre Team: IP address 10.192.0.2, subnet mask 255.192.0.0, default gateway 10.192.0.1, DNS servers 10.192.0.2 and 8.8.8.8
The network switch and access points we are using are a D-Link DWS-4026 unified wireless switch and matching D-Link DWL-8600AP access points. The captive portal function is part of the switch's capabilities. The switch's IP is 10.128.10.1 and it redirects unauthenticated HTTP connections coming via the wireless APs, to the captive portal page. Authentication is done via RADIUS.
Having previously attempted and failed to configure Forefront, I reinstalled the server and without Forefront installed was able to set up DHCP, DNS, NPS and RRAS roles such that wireless clients could connect and obtain an IP address, the switch's captive portal successfully redirected wireless clients, which were then able to log in using Active Directory usernames and passwords, and subsequently access the Internet.
I then installed Forefront on top of this configuration in the hopes that it might intelligently detect existing settings but this appears not to be the case.
I have managed to set up firewall rules which should allow the necessary DHCP, DNS and RADIUS traffic, along with the web access rules we would like (the main point of using Forefront is so that we can do web filtering and malware filtering) but while wireless clients are able to connect and obtain an IP address, they can't connect to the captive portal now.
Can anyone offer any advice or suggestions?
I wish to ask even if i tried to look many many forums and question that have been asked here it wont solve the problem...
Outlook works good receiving emails but sending emails does not work. I get on forefront TMG loggs an error and it looks like its blocking a specific port.
Does anyone know how to step by step fix this problem?
Thanks

Hi Team,
We have published a website via Forefront TMG and our requirement is to show the custom error pages based on the internal web server response (HTML Status Code). We don't want to do this in web.config of internal website.
Is there anyway to do this in TMG ?

We have had OWA setup for a few months and it works with no issues. In exchange we have the internal URL as https://servername.domian.com/owa and the external URL as https://mail.xdomain.com. Both have worked without issue and connecting to the mail.xdomain.com URL from internally would redirect you to the correct address.
Now have installed the TMG Client on all our TS servers and have it automatically configure the web proxy. Once we do that, we can no longer access OWA using the internal URL. We can connect with the external URL still, but we don't want our traveling users to have to use two different URLs to access OWA. If I manually remove the web proxy in the IE settings I can connect with no issues.
The TMG logs shows this when trying to connect using the internal URL:

|
<id id="L_LogPane_User">User: </id>anonymous In the rules for the Internal network we have "bypass proxy for addresses in this network" and "directly access computers in this domain" with our Exchange server listed. I'm not sure what the issue is and was hoping somebody could shed some light on this. Thanks in advance for your time! |

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.
We have a two node TMG implementation with no EMS. On each node I have tried setting the HTTP proxy as some posts suggest (either through the netsh command line or within IE). That got rid of the 80072EE2 error but now I am getting a 80244004 when attempting updates. The only posts I have found on that error seem totally unrelated (usually referring to ESET which we are not running).
I also added a firewall policy in TMG to allow HTTP and HTTPS from the localhost of each machine to the Windows Update sites (a predefined list in TMG). I am able to browse external sites from each machine just fine. FWIW according to the page below that error code means the SOAP client failed to connect.

If anyone has any ideas any suggestions would be greatly appreciated.
Thank you.
2 TMG servers - back TMG member of the domain, front TMG not a member of the domain, both running 2008R2 and TMG 2010. Trying to publish Exchange OWA, Active Sync, etc. OWA works internally. Create OWA publishing rule on both TMG server, back end rule tests fine, front end errors out. On the back TMG I get the following two events each time I test the rule:
Description: The Web Proxy filter failed to bind its socket to 172.24.0.4 port 443. This may have been caused by another service that is already using the same port or by a network adapter that is not functional. To resolve this issue, restart the Microsoft
Firewall service. The error code specified in the data area of the event properties indicates the cause of the failure.
The failure is due to error: An attempt was made to access a socket in a way forbidden by its access permissions.
Description: A problem preventing the Web Proxy filter from binding its sockets was resolved.
And in the log I see:
Denied Connection TUSPROXY2 10/31/2012 8:34:27 AM
Log type: Firewall service
Status: The policy rules do not allow the user request.
Rule: Default rule
Source: External (172.24.0.1:11498)
Destination: Local Host (172.24.0.4:443)
Protocol: HTTPS
I have OWA working between my Exchange 2007 server and the default IP on two servers. I added new IP addresses to the NICs and created Web Listeners on each using a certificate created by our internal PKI. No issues with the certificate chain. Wierd thing is it was working and then stopped while I was trying to resolve and issue getting Active Sync to work but I don't know what changed. Both TMG are using forms and "No delegation but client may authenticate directly" It seems like the publishing rule on the back TMG isn't opening the port so the connection is denied by the default rule. My gut feeling is the rules can't be identical because one server is in the domain and the other isn't but I am not sure what to change.
Thanks in advance

I have two TMG firewalls (on two separate environments). One is version 7.0.9193.540 and the other is version 7.0.9193.500.
Our Android users are able to use the L2TP IPSec VPN client (with PSK) with version 7.0.9193.500 but not with .540. There is no error message on the Android device- it simply times out and says "unsuccessful".
Does anyone know of a website that tracks all the version-changes of TMG?
Any other suggestions as to how to fix this issue?
How exactly can I monitor the connection attempt on TMG? What filter settings should I use?
Many thanks

Hi,
Which of the following will work on a TMG server with a single NIC:
Thank you
SK
Hi Guys,
so far we had running an single ISA 2006
server (running on 2003 std.) on our network which is publishing our Exchange OWA 2010 & ActiveSync, Sharepoint-Sites and so on. This works perfekt, however, for security purposes and for a unique server landscape, we
now wanted to install a new TMG 2010 server on server 2008 R2.
We tried this change already two years before and it ended up in that we were not able to use the new TMG because not all of our public IPs on the external NIC were reachable from the internet (outside the network). So, we thought of a bug, we waited and now took a second try - even with all the new service packs and hotfixes released meanwhile... and -what shall i say- it still doesn't work.
What we did: We first installed the new 2008 R2 server while our old ISA 2006 had still been in service. No problem so far, the configuration (similar to ISA 2006) worked good and even the import of the old ISA 2006 configuration had been
no problem. Just the IP adresses of the external NIC had of course not been the same like those used on the still active ISA 2006, because both servers are located in the same network and connected to the same router. We used some IPs that still had beend
free within the same range:
The networks address is aaa.bbb.ccc.80, the gateway (router) address is aaa.bbb.ccc.81 and the ISA is hosting addresses aaa.bbb.ccc.82 to aaa.bbb.ccc.90 and the new TMG is initially (updateing, testing pruposes, etc) hosting aaa.bbb.ccc.91 - aaa.bbb.ccc.94
(network mask is 255.255.255.240) - at least both are using different ranges within the same network. Until here everything on the TMG worked fine - internet access, published SharePoint test sites, PINGs, etc
On the day we wanted to switch to the new TMG, we shutdown the ISA and added the remaining ISA addresses to the TMGs external network card. We sat the right NAT IP for external communication - but only a few of the new adresses were reachable from the internet. From the TMG itself or within the internal network, the access to all published sites was no problem. But only one listener of the new addes addresses was working (and responding to pings) from the internet while the rest was neither reachable nor pingable.
What we tried:
- disabeling & reenableing NICs, restart server & services, reconfigure the listeners with other public IPs from the external NIC,...
- logging of access to the published sites (no access had been recognised)
We are quite desperate with this issue because -if you believe in search engines - nobody on the whole web seems to have this problem - but we are able to reproduce it again and again :-/
Any ideas on this issue? We ran out of them...
Thanks in advance!
Is using a wildcard certificate for L2TP vpn's on an ISA2006 server supported? If yes, can anyone point me to a good manual for configuring L2TP on ISA?
