Hi All.
Maybe this is a silly question but so be it.
I have been using ISA 2006 for about 6 years and all clients are configured as web proxys with Proxy settings in the Browser of client machines.
I read last night on TMG forum that this configuration only allows Http Https and Ftp Outbound.
Does this mean that my Outbound rule on ISA which specifies All Protocols is in fact only allowing those protocols ?
On another note for business use do you think its fine to just allow Http Https and FTP outbound (We have our own internal dns servers as well as Exchange servers) for normal clients.
Our servers are on a Seperate Vlan so I will allow them full access out only.
Will they be able to access most web content.. ??
Any help or experience will be appreciated.
Thanks Shaun.
hi,
I am new to this product now we are installed TMG 2010 our office for enable VPN Access to Client , the problem is for assigning IP to client how can i enable DHCP relay Agent in TMG 2010.
Anybody have knowledge pls give me the solution
Thanks in Advance
TMG 2010 RC Standard Edition
Windows 2008 R2
When I installed TMG the internal NIC had the ip address 192.168.188.2. After configuring I changed the address to 192.168.188.1. Now the following error is logged in the event log:
The IP address specified for communication between this Forefront TMG computer (192.168.188.2) and other array members is not bound to a network adapter installed on this computer. The IP address specified for intra-array communication must be bound to a network adapter installed on the computer.
Where can I change the address?
Why is there an intra-array address when the server is not an array member?
Hi. all
I m trying to set up a NLB with a two TMGs.
When I try to configure NLB with Unicast, I can notpingeither thededicated IP or thevirtual IP. For this reason I cannot publish my Exchange.
The two TMG are not in array.
Also I do notrequirenlbenable in internal cards.
please help me..
I need to know the best environment configuration for IPs for Forefront Implementation:
Well , i will setup an Edge Forefront Environment , so i have two Ethernet Networks on Forefront Server as following:
Internal Forefront Server Card ( Internal FFS):
IP: 192.168.2.254
Subnet: 255.255.255.0
Gateway: Empty
Primary DNS : the DNS IP for my Domain Controller as its have the DNS server.
External ForeFront Server Card ( External FFS):
IP:
Subnet:
Gateway:
Primary DNS:
then , i have direct modem ( speedtouch black from my ISP)
as i know ,
- modem directly connected to the External FFS
- normal switch connect to Internal FFS plus Servers and users in the my internal network.
the question is focus on External FFS:
Do i have to connect internet modem directly to the External FFS ? then Create BoradBand Connection to Connect on ADSL Account through Modem, how do you suggest Configuration?
OR i have to connect normal router between the modem and External FFS? Whats Configuration?
Note: i have a Static IP.
We have 2 subnets (A and B) connected via a wireless bridge and router (with Interfaces A and B). Each subnet has its own ISA server in firewall and proxy mode.
On subnet B the default gateway is the ISA server's LAN adapter. IE LAN settings are set to 'Bypass proxy for local addreses'.
When I try to access the web interface of a switch or access point on subnet B whilst on subnet B (regardless of the default gateway on the device itself) I receive the dreaded 'Error Code 64: Host not available'. The only way to access the device in question is from Subnet A when the default gateway is set to interface B of the router connecting the two subnets.
Does anyone have any idea how I can solve this problem?
Hello all,
I am trying to cut down on useless chatter in the log, specifically from Checkpoint Firewalls that sit in front of TMG Arrays.
Log entry as follows (occurs on both internal and external interfaces) :
| Denied Connection | xxxxxxxxx 25/07/2013 15:42:06 |
|---|---|
| <id id="L_LogPane_LogType">Log type:</id><id id="L_LogPane_FirewallService">Firewall service</id> | |
| <id id="L_LogPane_Status">Status: </id>A packet was dropped because Forefront TMG determined that the source IP address is spoofed. | |
| <id id="L_LogPane_Rule">Rule:</id>None - see Result Code | |
| <id id="L_LogPane_Source">Source:</id>0.0.0.0:8116 | |
| <id id="L_LogPane_Destination">Destination:</id>Internal (x.x.x.x:8116) | |
| <id id="L_LogPane_Protocol">Protocol:</id>[Enterprise] xxx Checkpoint Clustering [UDP8116] | |
| |
This traffic is expected as it is normal between Checkpoint firewalls. I can't figure out the right combination of settings, though, to keep this out of the log. The problem seems to be with the source IP being 0.0.0.0 - I can't add that to any network nor define it as a computer object. I tried making an access rule matching the protocol, but, seems this is picked up as spoofing so does not get that far in rule processing.
Any ideas?
Thanks in advance,
Hi All
We are having some issues getting a VPN set up to use a smart card for its credentials. It works just fine when using a username and password, but fails with the following error when using a smart card:
The client could not be authenticated because the EAP type could not be processed by the server.
This appears in the Security log as an audit failure. Above it is the details of the username, client IP etc which all appears fine.
The network setup is as follows. All servers run Server 2008 R2 Standard with SP1. All clients run Windows 7 Professional with SP1 64 bit and are domain members. We have a DC at 2008 R2 Forest Functional Level. We have also installed a CA on this server, and have duplicated the Smartcard Logon template to V2 (Server 2003 Enterprise). We have another server running TMG 2010. This has 2 network cards, one for local LAN and one for WAN. It is set up as an edge firewall. We have enabled the Remote Access (VPN) settings in the console for TMG. We have it using PPTP and allowing a group called VPNUsers access.
When we use our client PC to access the VPN using a username and password, it lets us in with no problems. We reconnect to the domain network and plug in our smartcard reader. The user we are logged on to the PC as is an admin. They have also installed an
Enrollment Agent certificate into their local store. Using this user, we then enroll on behalf of, and then put in the name of our user. It requests the smart card be inserted. We do this and the enrollment goes through fine. Log off of the PC and back in
as the user instead of the admin. Change the VPN to use smart card instead of PEAP or EAP-MSCHAP-V2. Then it fails to establish the connection with error code as shown in the attached image
I have tried a number of different smart cards, readers, and tweaked several settings on both the client and server, but I am coming to the limit of what I can do. Is this something anyone has come across before? Have I missed a step in the setup of the VPN or client? Any help would be greatly appreciated.
Many Thanks
Iain
Hello
I'm trying to setup TMG to allow the hybrid configuration wizard to run.
On my TMG the autodiscover and activesync share the same listener. OWA uses a different one.
The hybrid TMG setup doc states I have to turn off authentication and allow all users however when I do this our activesync breaks. Its setup for basic auth.
Is there any way I can get activesync to work without the listener authentication? Or get Office 365 to work with basic authentication?
I cant change the activesync url or IP as its already in everyones phones.
cheers
We are using TMG 2010 and Exchange 2010 to publish OA, OWA, and ActiveSync. Currently I have setup a separate web listener for ActiveSync which requires SSL Client Cert Authentication. I am having issues getting it to work.
I am trying to use the same wildcard cert for both web listeners but I am not sure if this is possible (mail.company.com and activesync.company.com). Both names are in the SAN, the web listeners each listen on a separate internal IP which have corresponding
public IPs NAT'd to them.
Is this possible?
Hello
I have a domain with 70 users, server 2012 DC with server 2012 secondary DC, internet connection is by web proxy of ISA Server 2004.
I cannot do nslookup or ping from any of DC or user comp. But there is normal internet connection!!!
C:\Windows\system32>nslookup google.com
Server: dc.energinst.am
Address: 192.168.1.1
DNS request timed out.
timeout was 2 seconds.
DNS request timed out.
timeout was 2 seconds.
*** Request to dc.energinst.am timed-out
....................................................................................................
C:\Windows\system32>ping www.google.com
Ping request could not find host www.google.com. Please check the name and try again.
I checked DNS and it is ok. It seems the only reason can be ISA, but I don't know ISA server and it is configured not by me. How can I check if ISA is blocking something?
Good Morning All.
I'm having problems with a new installation of TMG under Hyper V. Initially the Microsoft Forefront TMG Firewall Service (wspsrv.exe) would not start, directly after the installation finished, this is the windows log entry:
"Microsoft Forefront TMG Firewall Service could not create or access the ScanStorage folder C:\Windows\TEMP\ScanStorage."
The directory did not exist, so I created it and tried to restart the FW Service to no avail: Windows Log entry:
"The Microsoft Forefront TMG Firewall service terminated with service-specific error %%213017"
I installed TMG SP1, no change. I managed to start the TMG Firewall (wspsrv.exe) by changing the Service logon properties to use the local system account rather that default Network Service. (I know this isn't standard practice but it's a lab box). Now the Microsoft Forefront TMG Control (mspadmin.exe) is taking at least 5 minutes to start. Other issues are now appearing, windows log entry:
"Forefront TMG was unable to decompress a response body from ***** because the following error occurred: The data is invalid.. This error may occur when the available memory is insufficient, the response is corrupted due to a network problem, or the server returns an illegal response.
I destroyed the suspect TMG slice, deleted the VHD's, rebooted the host and re-created the TMG slice. Exact same errors! As yet, I haven't installed Software Update 1 or 2. I have 2 other concurrent TMG installs running on this box and they run flawlessly. I'm hoping it is not the underlying lab box.
Host is 2008 R2, fully patched, 24GB, 4GB free at all times, 2 physical NICS each with their virtual switch. I have assigned 4 virtual CPU's to the suspect TMG slice and 3.5GB of memory, Edge setup.
Regards,
Steve.
Installed TMG SU1 & SU2, rebooted, no difference. I am still receiving the decompression error's. :(
I have added websites on my TMG HTTPs inspection and excluded these sites from it. However the websites are still getting blocked with below mentioned error. These are https websites.
Error Code 12229: The page was blocked by HTTPS inspection. Date: 7/29/2013 5:14:33 AM [GMT] Server: MCR-TMG-01.parco.com.pk Source: Proxy

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.
