ISA Firewall Client bypass content filter
Hello
We have ISA 2006 and TMG 2010 with Websense 7.6.2 as content filtering application. Websense plugin is installed on ISA/TMG nodes and it filters web traffic based on ACL. ISA/TMG is placed on intranet (behind firewall) with NLB in place.
The issue is with firewall client. Users with Firewall Client just clear the Proxy settings in any browser and bypass the filter. This allows them to navigate to any https site (which are blocked by Websense) as if the content filter was not working. At the same time users cannot access http sites which are blocked by Websense.
This happens only with machines installed with firewall client.If FW client is removed then everything works normal.
I tried to fix the problem by adding a new Setting to the Firewall Client Application Settings for all browsers.
This is how to do it:
Go to “Configuration” then “General”; There you will see the option “Define Firewall Client Settings” on the right pane;
Then choose “Application Settings” page and click “New…”
In the “Application Entry Setting” box configure as follows:
Application: iexplore Key:
Disable
Value: 1
Ref: http://www.mmco.com/forum/topic.asp?TOPIC_ID=27963
It worked for me for few days. But again I am facing same issue. Websense said it is not the issue of ISAPI filter which is sitting on ISA.
Already gone through forums, but no luck.

Android VPN connection keeps droppingseconds after connecting
I setup L2TP/IPSec VPN with PSK on TMG 2010 but when connecting an Android device, the VPN connection keeps dropping seconds after connecting. All other devices are fine.
I have found the hotfix that would almost certainly fix the issue, the link to it however (http://support.microsoft.com/kb/2722729) isn't working.
I've checked if it is included in this month's updates for TMG but it isn't.
Does anyone have any suggestions? Surely, there must be thousands of Android users out there who connect to a TMG firewall for their VPN.
Thanks

Error publishing non-web servers
I need to publish a non-web server but when I try to access the server (port 9100 and 1194) I cannot, the TMG does not match the publishing rule and goes directly to the permanent rule, so all connections and rejected.
This is my TMG configuration:
Perimeter: 10.0.0.1
Inside: 10.5.5.2
Server : 192.168.120.5 is inside and I have some routes for it.
ports: 9100 tcp->80 , 1194 (tcp/UDP) -> 1194
All traffic enters from the perimeter, it is like an external network, so before the publishing rule I added a network rule (NAT) for that server.
Could you help me please?

Need some guidance on setting up TMG 2010 Standard in an all virtual environment to protect Exchange Web Services
We currently have 2 ESXi 5 hosts in a cluster running about 30 VMs.
We are running exchange 2010 and would like to publish our OWA, ActiveSync, OAB, Outlook Anywhere to the internet.
Our requirements are to set up TMG 2010 as a VM on this same cluster.
Is this possible?
My thinking was to use 1 physical NIC connection to each ESXi host to create a new virtual Network and bind that to one of the vNICs in the TMG2010 VM and then create a 2nd vNIC in the TMG2010 VM which is binded to the internal domain network that all VMs are using.
How can I configure this to keep exchange safe as well as not expose our ESXi hosts to attack?
I need to figure out what to tell our networking people we need for that 1 pNIC that needs to be exposed to the internet. Or if we should still keep it behind firewall and just pass through specific port traffic to help protect ESXi but still allow ports that TMG2010 will need to publish Exchange Web Services.↧

HTTPS listeners and multiple external IP addresses
Hi,
I’m having a small problem with HTTPS listeners and multiple external IP addresses. TMG 2010 has two External IP addresses on the same NIC, the main IP xx.xx.xx.50 and the second xx.xx.xx.51. The .50 address is used for OWA and ActiveSync and I would like to use the .51 for Citrix Secure Access Gateway, which requires all https traffic sent to Z server. (basically publishing a https server.)
My problem is no https traffic seems to hit the TMG server on the .51 address, if I ping the .51 address you can see the pings in the TMG logs. If I try to access our site using http you can see the traffic being blocked by TMG but if I try to access the site using HTTPS no traffic is displayed in the TMG logs. (which isn’t helpful)
Any ideas why I cannot see the https traffic within the logs for TMG???? (As this greatly help me troubleshoot the problem)
Config: I have created a server publishing Rule, which listens for ‘https server’ traffic on the selected External .51 address.
TMG 2010 SP2, setup as Edge config with ISP Redundancy (different ISP) and web chaining to an external Smart host (messagelabs)
Server 2008 R2 SP1

TMG Site to Site VPN
So I have a site to site VPN connected between a router and the TMG 2010 server
The problem I am having is that the traffic is not being routed by TMG
When it hits the TMG server it goes no where
From what i can tell all the right routing is in place for the server, TMG automatically created it when i set up the VPN
Any suggestion what could be blocking it?
I am running on Server 2008 r2 enterprise

TMG ISP Redundacy issue web publishing related
Hi, I'm currenty having a publishing problem using TMG ISP-R.
We have 2 Web publishing rules with 2 HTTPS Listeners that use 2 IPs from 2 ISPs, so each listener has 2 IPs assigned, one from each of the ISP.
Whichever listener has the second IP Address of the NIC card assigned to, that listener fails to open the web page from outside. Let me give an example to explain this better:
2 Publishing Rules: OWA and Secure Web.
2 HTTPS Listeners: OWA Listener, SWeb Listener.
2 ISPs: ISP1, ISP2
2 IPs per ISP on each external NIC on the TMG Server: External NIC 1: 10.1.0.1, 10.1.0.2
External NIC 2: 10.2.0.1,10.2.0.2
When OWA Listener is using IPs: 10.1.0.1, and 10.2.0.1, with the ISP-R working, it works fine.
When OWA Listener is using IPs: 10.1.0.2, 10.2.0.2, with the ISP-R working, it only works using the first ISP, not the second one.
and the same thing happens with the second listener if I switch them back and forth.
I've already configured ISP-R with only one Default Gateway on one NIC and no Gateway on the other and the adding the second default gateway using the ISP-R Wizard.
Also tried configuring the ISP-R with both gateways set on each NIC adapter, with this configuration the response is quite different, the listener using the second IPs from the External NICs don't work at all when both ISPs are up, but when I turn one or the other down then it works.
It's quite difficult to explain it but hopefully someone gets it, if not, let me know.
Thanks for the replies.

HTTP, HTTPS traffic is not working when traffic is forwarded with PBR from diffrent subnet other than TMG subnet
Hi,
I have one client subnet other than TMG subnet, from which I am forwarding the WWW, 443, 8080, ICMP traffic towards the TMG proxy with cisco PBR. ICMP traffic is working fine. Other TCP traffic like HTTP, HTTPS is not working and client is getting timeout. On the other hand if the client and TMG in same subnet and if I am assigning the TMG IP as the client default gateway (in Client network adapter), the all traffic is working fine.
I opened a TAC with cisco and they confirmed that there is no issue with PBR as it is forwarding traffic to TMG.
Is there any known issues if the client and TMG server in diffrent subnets?.
Is it possible to resolve the issue even if the client and TMG in diffrent subnets.?
Thanks

Case Sensitive URL cache!?!?
Hello,
We use TMG to publish websites and are having major issues with TMG's cache feature, we do not use CARP as this was causing us problems also.
The problem we are having is 1 URL can be cached twice inside the cache with 2 different Character Case URL's, I can only see this using the TMG cache directory tool, let me explain more.
2 URL's:
www.google.com/BUSINESS
www.google.com/business
Would appear as 2 different cache directories inside my cache, and cause issue with webiste updates as this holds on to out of date .dlls etc and makes our life a nightmare. We have spent alot of money on the equipment used for caching and don't simply want to resort to turning it off...
Any ideas?

ISA 2006 Publishing SSH not recognised
Hi,
I'm trying to publish SSH from external to a server in our DMZ. I've read a fair few other blogs but nothing is working for me, this is what we have...
external client using WinSCP try to access a url which resolves to a public IP which is NAT'd to a private IP on our ISA server. (via Cisco firewall)
New "Non-web server publishing rule" created which listens on the private IP address above and directs traffic to our DMZ server (ISA has 5 NIC's) New Protocol created for "SSH-inbound" on port 22 inbound TCP.
However when i look at the logs, the rule and protocol do not get recognized and the default rule sees the traffic using the default SSH protocol instead of the User defined "SSH-Inbound" one i created earlier.
Things i have tried...
1) Changing "to" requests appear to come from ISA
2) adding secondary connection ports 50000-51000
3) creating a non web server publishing rule for FTP traffic and changing default ports to 22 inbound
Network Rules
I have a network rule relationship from DMZ to External (route) as this is bidirectional i'm assuming i do not need a External to DMZ route relationship rule
Any Ideas?
Thanks

Unable to publish web site on localhost in TMG 2010
Unable to publish web site on Localhost in TMG 2010
Hello, I am trying to publish a simple static web site in W2K8 R2/IIS 7/TMG 2010. TMG is set up as an Edge Server and the box has internal (192.168.254.xxx) and external (Comcast modem static IP) nics There is a simple TMG Web Server publishing rule with the external name www.estarmail.com and the gateway server internal IP. Very simple setup and the web site does display when I click the “Browse *:443 (https)” link in IIS Admin. The “Browse www.estarmail.com on *:80 (http)” link fails with “Error Code 10061: Connection refused - When the gateway or proxy server contacted the upstream (Web) server, the connection was refused. This usually results from trying to connect to a service that is inactive on the upstream server.“
The DefaultAppPool identity has access to the inetpub/wwwroot folder and there are bindings for both http/80 (with external name) and https/443. I am able to access the internet internally and from the gateway edge server and can send and receive emails with an internal Exchange hub server.
I am unable to access the site on port 80 from anywhere inside/outside/localhost. It looks like the main problem is that TMG does not have a route to localhost. I get a variety of errors:
10051 A socket operation was attempted to an unreachable network
10060 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.
12202 Forefront TMG denied the specified Uniform Resource Locator (URL).

Forefront TMG vpn client cannot access internal resource
Hi
I setup forefront tmg 2010 pptp VPN server. The VPN client can connect to the server with IP address 169.254.x.x and can ping the server RAS interface 169.254.x.x. However, it cannot access any internal resource. I have an old server win 2003 with ISA 2006 VPN can work with the same network setting.
I have the server log when connecting to TMG VPN and find that " A packet was dropped because it cannot be forwarded since its
incoming and outgoing network interfaces have different zone indexes for the
packet's zone level"
Could anyone help on this? Thanks You.
Best regards, Wilson

TMG Non-Web Publishing Rule - to multiple servers errors in console
I have a TMG Standalone Array we are using it for reverse proxy. I am trying to publish services for our Anti-Virus product from our DMZ back to our LAN. We have more than one server that runs the services for failover purposes. Each server has its own IP / HostName and uses the same ports for communication. I didnt see a way to setup a farm for the non-web publishing rules so I created one Listener with all of the needed ports and then used that same listener for multiple non web publsihing rules one for each server. When I do this I get an error generated in the console. If I only publish one of the servers the error goes away. Is the problem that I cant use the same protocal / ports for multiple servers? If not how would I publish multiple servers in a non-web publishing rule? I dont understand the part about the duplicate name on the network? There are no actual host names in the non-web rules and each rule has its own IP address for each of the servers.
Here is the error it repeats with the different ports numbers I have setup in the protocal.
The server publishing rule xxxxxxxxxxxxxxxxxxx, which maps
x.x.x.x.:8888:TCP to x.x.x.x:8888 for the protocol xxxxxx, was
unable to bind a socket for the server. The server publishing rule cannot be
applied.
The failure is due to error: You were not connected because a
duplicate name exists on the network. If joining a domain, go to System in
Control Panel to change the computer name and try again. If joining a workgroup,
choose another workgroup name.

I can not make a vpn connection from client to external
Hi;
I have a Local Network, I've installed Microsft Forefront Server 201o with SP2. Everything is working fine but my manager is used for VPN and Socks to connect Internet sometimes. When he tries to connect internet dialing box shows that "Port Opened." but it's not connecting and after trying several ports (PPTP, L2TP, ...) shows Error and connection unsuccessfully.
Anyone has an idea for how to solve it?
These rules were correct on ISA Server 2004 but in TMG not working properly. Rules Details
Internal range: 192.168.1.X
External connection IP: 172.16.1.10
Internal-LocalHost/ all outbound traffic | Internal | Localhost
LocalHost-Internal/ all outbound traffic | Localhost | Internal
Internet users/all outbound traffic | Manager (192.168.1.20) | External (These Rules work fine)
