TMG Roll ups

$

0

Hi,

I am using TMG2010. A question is regarding Roll up installation. I have installed a Roll up 5 on TMG 2010 SP2 server.

My question is, is it mandatory to install all the Roll ups from (1 to 5) on TMG 2010 SP2 or only Roll up 5 is enough?

Please also suggest me the order of installation of Roll up?

Thanks

Supporting of Broadcast and Multicast in TMG 2010 !

I have installed TMG 2010 SP2 at Windows 2008 R2.

So, as I read TMG blocks as broadcast as multicast.

And such built-in only one way default behaviour is not right.

I want in my own (as user/admin) define whether it is necessary to me or not as following there have to be ability to switch it on/off such option, for example as checkboxes for each network (address range) defined by default/user - one for broadcast and one for multicast.

So, please add such functionality to kernel mode driver and to service in the next nearest SP or rollup.

And/or tell how is it possible to switch it on at Tmg 2010 SP2 and later.

There are some important services relying on broadcast: NetBios, Dhcp, some Alladin hardkey protection, some special soft.


If somebody of MS techinians will send registry parameter for this or specially designed driver, all will under my responsibility only.

Redirect external URL to an internally hosted application

I have created a application internally in my domain and the url for that internal application is https://server1.mydomain.local/something.

The users are accessing a public link https://abc.mydomain.com and they get the login page of Microsoft TMG. They login and when the credentials are validated they are redirected to https://server1.mydomain.local instead of https://server1.mydomain.local/something. I have used link translation and it is not working for me. 

I am using Microsoft Forefront TMG 2010. Please let me know if I am missing something or there is some configuration change that needs to be made.

Thank You

TMG Rollup Question

$

My question is related to patching and rollups for TMG 2010. I am in an Enterprise array setup, and question is current EMS server is running Microsoft TMG EE version 7.0.7734, while all the other array members are running SP2 Rollup 3. I am planning on patching all the TMG proxies to rollup 5, and would it be okay to install SP 1 on the EMS and then SP 2 and then Rollup 5 before i proceed with updating the rest of the array members to rollup 5? I am kind of afraid because as of now no service packs or rollups are installed on the EMS it just running version 7.0.7734. Any advice would be great. Thank you very much.

Lost Dual Monitor access

Have a customer that we setup Remote Desktop Dual Monitor Support for UAG and had been working fine till this week.  We lost internet connectivity while they were in a remote connection.  After the brief connection loss (less than two minutes) only one monitor will display.  We have deleted all IE11 settings and rebooted the UAG server but nothing helps. 

Now the weird part, I'm able to login to the machine and see dual monitors.  I'm able to use the customers login and see dual monitors.  I'm doing this on the same subnet but will be checking later on a remote connection.  Everything so far points to an issue on the local home machine but what it could be I have no idea.

Any thought would be great

tmg 2010 destination in log and blank webpage

$

sorry if this is a stupid question but this has been doing my head in all day.

We have an ISA 2006 box which i have tried to migrate to a VM running Server 2008 r2 with TMG 2010. This is purely for internet access.

As is the case with the ISA box, the new server is configured as an edge firewall.

On the TMG server itself i can get to the internet fine and can get to the internal network fine.

BUT From a client PC we can't browse the internet. It tries loading the page and just when it looks like it will work, no error message, just a blank white page.

The TMG logs show client IP as my PC and destination IP as the IP address of the internal adapter and not the ip address of the webpage in question. This doesnt sound right.

Any tips on what i am doing wrong?

Install SCCM Client on TMG Array with IPSec tunnel

$
0
0

We currently have to standalone TMG arrays that are connected with an IPsec VPN tunnel. We have an SCCM server located in 1 Datacenter behind the array. In that DC, all servers, including the TMG servers, can connect to the SCCM server. In the other datacenter (DC), all servers are able to traverse the tunnel and communicate with the SCCM server.

The only issue is the TMG array at the other end of the tunnel. Neither of the servers can reach any of the servers behind the tunnel. When I look at the logging, it says the adapter is localhost, but the client IP is the public IP of the TMG server. The logging on the other side of the tunnel (DC with SCCM) shows no connection attempts. There are explicit firewall rules to allow the traffic from localhost to the network on the other side of the tunnel.

How do I configure the TMG array to use the IPsec tunnel when communicating with servers on the other side?

Traffic rule between two sites

$

Hello,I have set up a Site-to-Site VPN between two sites in my domain.

Reading about it, one of the things I see in all the tutorial is about creating a rule like this one (on each of the two TMG machines):

TMG in the Main Office:

Allow all outbound traffic from: Internal / BranchOffice , to: Internal /BranchOffice

TMG in the BranOffice:

Allow all outbound traffic from: Internal / MainOffice , to: Internal /MainOffice.

All works fine but I don't understand why the machines in each lan have to reach the machines in the remote lan.

Would it not be more secure to allow only specific traffic? What if a virus reaches any pc in one of the lan, and goes to the other lan in the remote office?.

Thanks in advance!

Dumb Question - Traceroute through TMG

$
0

Hi Folks;

For a long time now something about my TMG 2010 install has bugged me - whenever I do a traceroute the firewall never shows up in the list - ie;

C:\>tracert ibm.com

Tracing route to ibm.com [129.42.38.1]
over a maximum of 30 hops:

  1     *        *        *     Request timed out.
  2    24 ms    11 ms    28 ms  x.x.x
  3    25 ms    12 ms    10 ms  x.x.x
  4    15 ms    16 ms    26 ms  x.x.x
  5    20 ms    19 ms    36 ms  x.x.x
  6    29 ms    36 ms    31 ms  x.x.x

So, the first hop should be my firewall but it never shows up.

As a guess, I created a rule for ICMP from internal to all networks (and local host) but that didn't fix it.

It's not a big deal but it would be nice if the first hop (the tmg 2010 machine) actually showed up.

This is the log file showing all denied requests from that traceroute machine;

Hi ...

I am using TMG 2010 SP1 as Edge FW on Win Server 2008 R2 having 02 NICs. The problem is that my TMG server providing internet services properly without any problem and delay, but when i ping and RDP my TMG it respond only for 40-50 seconds and after this time connection time out for ping requests and connection lost for RDP. also Ms outlook didn't send or receive email after 40-50 secs. When i restart my server it again start responding for 40-50 seconds only for once.

1. I have configured System policy editor to allow ping and RDP and created firewall rules to allow both protocols and same for MS outlook.

2. I have verified that both of NICs of TMG (Broadcom) are working properly and NICs Driver Ver. is 5.2.05

3. My TMG can ping all the clients and DNS, DC server. 

4. there is no updates KB2888049, KB2882822 and KB2913431 are installed on my Win Server 2008 R2 as i have read blogs about these updates are creating issues like that.

If any body have an idea about this mystry issue please help.

Cant Setup SP2 for Forefront Crypt Init Failed error 0x80090016

Hi guys,

im trying to implement TMG SP2 on our accept servers.

The current situations is as follows:

1 EMS server, 1 Internal Array (2 servers) 1x external array (2 servers). Logging is done in a separate SQL server Database.

Current Version is TMG 2010 enterprise Update 1 Rollup 4.

Array is proxy chained upwards.

Ive succesfully upgraded the EMS server to the new version.

When installing SP2 on the first server in the internal array (Reporting server) the setup crashes at the actionSetFwsrvSdToCSP

=========================

MSI (s) (34:84) [14:56:02:933]: Executing op: ActionStart(Name=SetFwsrvSdToCSP,Description=Sets the Firewall service security descriptor on the cryptographic service provider...,)

==========================

ive corrected the NTFS permissions on the folder C:\Programdata\microsoft\crypto\rsa\machinekeys.

restarted the server. Protected storage service is running, the server can contact other servers.

Can anyone give me a hint. I need to upgrade the rest of the servers before i can do this in production environment

also attached an image with the error on screen.

Spotty Internet and TCP_NOT_SYN_PACKET_DROPPED

$
0
0

I'm receiving a number of errors in the TMG log as:

None - see Result Code0xc0040017FWX_E_TCP_NOT_SYN_PACKET_DROPPED

This comes along with very spotty internet browsing from internal clients. I have a split-dns infrastructure, the DNS server in the DMz is my public DNS. Prior to this error and noticing spotty internet, I made changes to my DNS as I though that was the culprit, but the above issue remains the same. If I reboot the TMG server, the internet browsing is excellent for about 5 - 10 minutes, then falls on it's face. Stopping, refreshing, and multiple clicking on web links eventually gets there, but it's quite annoying.

A post I came across seemed to relate to the VLAN routing. The TMG INT LAN IP address is on the same VLAN as all my internal clients, connected to a cisco 3750G switch. I remember having this same setup years ago when I used ISA 2006. I do not have any ip default-gateway IP set on the switch. Any ideas on if I should make a change or how to resolve this error and internet surfing?

My Configuration:

I have 2 Cisco 3750G core switches in 2 separate rooms. They are connected by trunk port. I have a number of VLAN's as follows:

VLAN10 (Internal LAN) int ip 10.0.10.2

VLAN9 (DMz) int ip 192.168.0.2

VLAN20 (iSCSI) int ip 10.0.20.2

VLAN30 (vMotion) int ip 10.0.30.2

Inter VLAN routing is ok, systems from 1 VLAN can ping systems in another VLAN no problem. The TMG has a 3 NIC setup. DMz IP 192.168.0.9 INT_LAN IP 10.0.10.1 Ext IP x.x.x.x

All of the internal LAN servers and workstaions use the TMG IP as it's gateway. As suggested in a post I read, should I modify the cisco switch to include a default gateway of the TMG IP (10.0.10.1) and configure all of the clients connected to the switch to the VLAN's interface IP of 10.0.10.2? Should I add a static route? Should I add a default-gateway on the configuration of the switch? Any assistance or suggestions would be appreciated. Thanks.

TMG 2010 network adapter losing connectivity after application of MS updates for October 2013

$

Shortly after we applied the Microsoft October 2013 updates to our TMG 2010 SP2 server we started experiencing loss of connectivity on our Internet facing adapter (could not longer ping the gateway etc).  A reboot would resolve the issue.  The problem kept recurring so we removed a couple of the networking related updates for October (http://support.microsoft.com/kb/2888049 ) and (http://support.microsoft.com/kb/2882822 ) as a test.  After these were removed the problem stopped.

We inadvertently reapplied these two updates during the November 2013 update cycle and the problem happened again. We removed the updates and everything is back to normal.

Just wondering if anyone else has applied these two updates to their TMG 2010 SP2 server and experienced any unusual issues?

Thanks
