≪ Previous: FTP upload issue with TMG 2010 SP1

hello. I just did a stock "by the book" install of FFTMG 2010 with two NICs

with the default policy I was able to do M.S. updates - through SP2 for FFTMG 2010

from the console I went to browse with IE11 to look for rollups for FFTMG 2010 but cannot browse

I ran the web access policy wizard with no inspection or malware detection and that gave me one rule in the firewall policy section and one rule in the web access policy section

my test client workstation win7 enterprise can browse using the TMG as a gateway or also as a proxy on port 8080

when I browse to certain sites from the TMG console that are http I get partial results mostly with text and some misplaced pictures

it seems that https sites are problematic too - not painting anything or saying "this page can't be displayed" after pressing the refresh button, or also just displaying some test on the left of the page at for examplewww.microsoft.com does this after switching to https

using my test workstation I downloaded the BPA - it ran saying the bpa could not be updated - perhaps for the same reason that I cannot browse

I got one only of these

Forefront TMG detected Windows Filtering Platform filters that may cause policy conflicts on the server ISACAC3. The following providers may define filters that conflict with the Forefront TMG firewall policy: Microsoft Corporation.

I think I am missing something small, but do not know what - I have searched quite a bit to no avail

Can I please be directed to an article that addresses this issue or provided some guidance?

Thank you for your time......

Hi All,

We restrict all our Internet traffic from out datacentres and use white lists to control what servers can access on the internet. This has worked great until recently, it seems that some of our traffic is beeing dropped due to the outbouond traffic protocal beeing deteched as Branchcache Advertise, I cannot see anything obvious with our system to cause this. I have this feature turned off.

Has anyone had this or who can advise hoe I might resolve this issue.

Thanks

≪ Previous: Branchcache Advertise Protocal instead of HTTPS

I installed Outlook 2010 about 3-4 months ago. Two outlook connectors were added along with an account connected to an Exchange server. Two days ago when I tried to retrieve outlook connector emails, I received a security check from MS. I input the numeric group in the box provided. I still cannot send or receive emails because the error is consistent (80040126) and the note that 'the connection to the server is offline.' Is there some way I can reset the security on my two outlook connector accounts so that emails can be sent and received from Outlook 2010? Thanks for any help. regards, milt (anotlim@Hotmail.com)

clients connected to the "VPN Client" network can't connect to internal network

≫ Next: TMG Reboot sequence

≪ Previous: OWA published via TMG does not timeout

I have the VPN Client network configure for 192.168.5.130/26 (.129 thru .191)

I created access route to allow all outbound traffic from the VPN client network to the particular internal network I need them to access ( 192.168.5.0/26)

I created a second access route to allow all outbound traffic from internal network ( 192.168.5.0/26) to VPN client network ( 192.168.5.130/26) ( I found elsewhere on this site an example of someone successfully connecting both network without this second rule, I've tried with and without the second rule).

Clients (Windows 10) can connect to VPN network with no problem and gets IP 192.168.5.13x assigned as expected.

I ping FTMG server at 192.168.5.5 ( FTMG server has this specific IP address configured on that network card.)

but I can't ping the IP assigned on the Routing table for traffic going to 192.168.5.0 (see routing table below).

below is the Ipconfig readout from the client after connecting to VPN server.

Most documentation I have been able to find about VPN setup leave you with a "now just configure access rules and your are done!"...

Would it help if the VPN Client is on a totally different subnet like 192.168.10.x or even 10.0.0.x? not sure if the proximity in addresses may be causing routing issues.

any ideas on how to solve this are welcomed!

Thanks in advance.

TMG Reboot sequence

Hello Everyone,

We have deployed Forefront TMG Enterprise Array with a centralised Enterprise Management Server and child servers.

We have faced issues after OS patching that all servers are restarted at once and then services on few TMG servers don't come up. What is the correct sequence to reboot TMG servers?

≪ Previous: TMG Reboot sequence

Hi all

I am going to implementing a TMG server in my corporation network

I have 4 subnets one for financial, another for managers, other for developers and last one for internet access.

So i assign a vm for TMG server with 4 legs.

The most important thing is that i have a ftp server with read only access from developers subnet and full access from other subnets.

Developers should not have internet access as well.

So i have some questions:

1) which type of tmg server ( e.g. edge firewall,3 legs perimeter, front firewall or back firewall) I should install?

2) what kind of client access (e.g. NAT Secure, web proxy, TMG client)I should implement?

3) how can I prepare ftp access as I want with TMG.

All answers have been appreciated.

TMG reverse proxy sending Client Hello as TLS 1.0, how to enable 1.2?

≪ Previous: Need link to Download Rollups for TMG2010 SP2 and Installation Steps in Commandline

I have a TMG 2010 running on Win2K8 [not R2]. It is used as a reverse proxy for outbound calls to another system using web-chaining. My client server calls TMG using HTTP, and then TMG connects to the external resource using HTTPS.

The external system is planning to disable TLS 1.0 so I need to upgrade TMG to TLS 1.2. I've followed the instructions to enable TLS 1.2 by creating the appropriate SChannel registry settings and rebooting: http://www.isaserver.org/articles-tutorials/configuration-security/improving-ssl-security-forefront-threat-management-gateway-tmg-2010-published-web-sites.html

When I inspect the traffic with a packet trace, I can still see the Client Hello that TMG is sending to the external server as TLS 1.0. Are there further changes I need to make to make it send a TLS 1.2 Client Hello?

≪ Previous: SurfCop for Forefront TMG

I am trying to load balance the internal interfaces of a TMG Standalone array with an F5. Here's the scenario. TMG array has a weblistener for internal requests to various internal websites (sharepoint mostly). The rules in TMG work when I direct client traffic (DNS entries) to the internal IP address of either server in the array. When I put an F5 in front of the TMG array and direct client traffic to it instead of the TMG's and I configure the F5 to have it pass 80 and 443 traffic back to the TMG none of the rules work. In the TMG Server I see the following in the logs "a connection was abortively closed after one of the peers sent an RST packet". What am I missing?

≪ Previous: Load balancing TMG's with F5

I have a bit of a problem that I don't see a solution for and was hoping that someone here may know of a work around.

I need to create a site to site VPN connection but the problem is that only one site has an internet available ip address. The second site used to but when its ISP upgraded its service, the site was placed behind an unknown number of NAT layers. Is it possible to create a workable site to site VPN connection in this case? Are there any 3rd party products that would router a VPN connection to a NAT-ed site? Creating a VPN in one direction is no problem but the return trip is problematic. And, since there are DCs on both sites, this is more than a simple inconvenience.

On a related note, is there a way to effectively test a TMG site to site VPN? It will show whether such a connection is enabled or not but are there any tools to verify that it is up and working properly?

Thanks
