SCCM Internet Based Client Communication

We have one primary server (which includes all the general roles) and two remote distribution points. Question is, after I configure the MP for internet clients (HTTP and HTTPS), setup the necessary PKI infrastructure, publish the site server FQDN to public
DNS servers, and install the internet client, how does it communicate back to the internal server? We don't have a DMZ and our primary site server is completely internal. If I add our external IP to public DNS the internet client can resolve this and our firewall
is open to HTTPS traffic. Once the client reaches the front facing IP how does it than contact a strictly internal management point and distribution point?

HTTPS client communication and IBCM don't change anything about how ConfigMgr works really. The traffic must still flow from the client to the client facing sites roles. Thus, you need to facilitate this flow of traffic no different than hosting a
web site that both internal users and users on the Internet access -- in fact, it is exactly the same from a network perspective.

  • Internet Based Client Communication can not be established

    Hi,
    I have one Primary Site Server and a Database Server. It was only using HTTP connection before. By reading several articles I created PKI environment and made SCCM communicate with a test client via https. I dont have DMZ, so I want to use the existing site
    server for both internal and internet clients communication.  
    To test https communication, I installed MS Project while Client Configuration Manager General properties showed Client Certificate=PKI and Connection Type=Intranet. So obviously it can communicate via https on intranet.
    To test HTTPS Communication on Internet side, I entered a public DNS manually on the client computer and deleted DNS records for that PC from DNS. I also editted hosts file on the client by entering sccm.mydomain.com with public ip address. I set firewall to
    allow 443 on that public ip address.
    I checked and the Client Configuration Manager General properties shows Certificate=PKI and Connection Type=Internet.
    First I entered the address https://sccm.mydomain.com from the test client I see a IIS8 Web page. Then, I tried to get a report which shows installed programs on a computer and report result was not reflecting the latest changes I made. So I am not sure whether
    https on internet is working or not.
    I noticed  that  Client Configuration Manager Properties Network Tab, Internet Based Management Point (FQDN) is blank. I guess there should be sccm server internet address(sccm.mydomain.com). I installed client manually with the command below meaning
    I already entered the internet address for SCCM but IBMP FQDN is blank.
    ccmsetup.exe /usepkicert smsmp="sccm2012.mydomain.local" ccmhostname="sccm.mydomain.com" smssitecode="XYZ"
    Please advise.
    1. How can I test if https working on Internet Side?
    2. Is it normal to have Internet Based Management Point (FQDN) as blank?
    3. Is there anything wrong with the design I am trying to implement above?
    Thanks a lot
    Yavuz Selim Atmaca

    Here's a guide I made (MP/DP in a DMZ) but it should work for your scenario.
    http://www.systemcenterdudes.com/?p=193
    Make sure that your certificate requirement are ok and that your server FQDN is publicly published and available.
    You must have an internet FQDN in your client properties. You can enter it manually, use a script or by using the ccmhostnameproperties in your client installation. (as you did)
    To test, I usually connect directly on the internet bypassing the corporate network. It's the best test you can made.
    Your scenario and troubleshooting steps are fine, you're probably just missing a minor thing.

  • SCCM Internet Based Client Management Client authentification certificate on untrusted forest

    Hi everybody,
    I'm installing a IBCM server of SCCM 2012 and i'm facing a problem related the client authentification certificate. My DMZ server is in another domain of the primary site and the is only a one way trusted between. I'm not able to push the
    client authentification certificate using GPO. Is there a way to get the that certificate?
    Thanks for your help.
    Guillaume

    First, there's no single client auth cert. Each client must have its own unique client auth cert.
    Next, issuing certs to a system can be done in many different ways including the web portal, AD auto-enrollment, and the command-line. In this case, AD auto-enrollment can work if you've set up cross-forest support in your PKI. That is nothing done by default
    though and is something you need to configure. You can certainly use one of the other methods however.
    I highly recommend you engage a more knowledgeable PKI resource though because doing PKI right is not easy.

  • Support for Internet based client Management - SCCM 2012

    Hi There,
    My Company wants to go for Internet based client Management in SCCM 2012 SP1 R2 and here is the design I'm proposing. I'm getting a bit confused at one point and need suggestion....
    Everything would work on HTTPS ( PKI Certificate based )... LAN and Internet.
    1 Primary ( with non-client facing roles installed ) on LAN with two site systems.
    - One Site System configured for INTRANET support only with MP, DP and SUP -> To support LAN users ( Allow
    Intranet-only connections )
    - One Site System configured for INTERNET support only with MP, DP and SUP -> To support Internet users ( Allow 
        Internet-only connections )
    The INTERNET facing site system is in DMZ network connected to parent Primary via Firewall.
    We want internet clients to talk to ONLY DMZ SCCM Site System and no connection to corporate LAN. We cannot open any ports for internet based clients to LAN.
    If this is the supported scenario, then why we need to put the Internet FQDN in the Primary server Site System property. This server would not be available to internet. It should only be my DMZ SCCM server client should connect for MP, DP and SUP and only
    this DMZ server should be accessible to client over internet.
    Also, what least ports should be opened between :
    - Parent Primary and its internet facing site system kept in DMZ
    - DMZ Site system and internet clients.
    Thanks in advance for your suggestions.
    Sam

    The FQDN has only to be specified on the Internet facing site system. You can leave this field blank on the primary site Server.
    Ports to Open:
    Internet --> DMZ Site Server:
    TCP Port 443
    TCP Port 80, if Fallback Status Point is installed
    DMZ Site Server --> Primary Site:
    TCP 135, 49152-65535
    TCP 445
    TCP 135, 24158 (fixed with
    http://msdn.microsoft.com/en-us/library/bb219447(v=vs.85).aspx )
    TCP 80, 443
    If you have some other roles installed, please consult this page:

  • SCCM 2012 R2 Internet Based Client Management

    Can someone give me a quick overview on how they are using Internet Based Client Management in their environment.
    Some helpful things I am looking for.
    IBMC -Should it be a separate server from Primary Site Server?
    What roles should typically be installed?
    A helpful Visio drawing would be great.
    Thanks!

    Hi Mike,
    Can you please help me with this...
    I brought the book : System Center 2012 Configuration Manager (SCCM) Unleashed and I need some clarification on Internet based client topic.
    Can you please let me know if this is a supportive design? I'm getting confused with statements in the book.
    Here we do not want internet based clients to connect to ANYTHING in LAN network. I have designed to have the entire internet facing Site Systems in DMZ, connected to the Primary server.
    If my design looks OK to you... then why we need to mention the Internet FQDN of Primary server in Primary Server Site System Property…. This server should not be visible to internet based clients….
    The most important point here is …we want internet based clients to talk to ONLY DMZ site system server. And we cannot open any ports for internet based clients to talk to Primary server kept in Chicago LAN.
    I'm not able to add the picture here... please let me know know the email address where I can send that.
    Thanks,

  • SCCM 2012 R2 Internet Based client management (ICMB)

    Hi All
    We want to use internet based client management in our environment ,can we use same FQDN for both 
    internet and Intranet ,what settings need to be done and which ports needs to be open for them,is it required to put 
    SUP site syatem in DMZ or it can download updates directly from internet by getting policy from MP.
    which is the best security practice ,putting MP DP SUP servers in DMZ or opening pots in firewall is there any third way?. 

    The most important thing is that the Internet FQDN can be solved from a public DNS (usually you don't want any of your internal names to be that).
    Also, yes your clients can download straight from Microsoft Update, but they would still require access to a SUP to scan for available updates.
    For some more information see the following:

  • SCCM 2012 Internet based client management

    I used the link below to get started. I'm testing now on my test client. The test client is showing Client Certificate: Self-signed. The connection type however is correct: Currently Internet. Also under Internet-based management point. The
    server name is correct. However when looking at the client's ccmexec.log. It appears to be trying HTTP instead of HTTPS. 
    http://www.systemcenterdudes.com/internet-based-client-management/
    Thoughts?

    If it shows a self-signed certificate the client won't be able to connect. The Internet-based management could be because you've provided it during the installation of the client, or if the client was on the intranet before, received via a client policy.
    If you just installed that client while not on the intranet, start with the
    ClientIDManagerStartup.log. If the client was working before on the intranet, start with the
    CcmMessaging.log.

  • Internet Based Clients and Native Mode

    Hi guys,
    I have a question.... We have SCCM 2007 SP2 running in mixed mode in the environment. Now we plan to support internet based clients. Here is the current Hierarchy in mixed mode.
    1 Central Server
    1 Primary Server
    3 Secondary servers under above Primary Server
    Now as the requirement is to support internet based clients and want them to support on office LAN as well when they come to the office....this is what I would be doing : ( Theoretically I know, I need the practical steps to achieve that )
    1. Get all the 3 PKI Certificates : Site Server Signing, Web Server, Client agent.
    2. Make sure all the required ports are opened in-between Intranet <->DMZ AND DMZ <-> Internet
    3. Migrate Central server from Mixed to Native Mode.
    4. Install another Primary Server on Intranet in Native mode.
    5. Create a site system server connected to newly created Native Primary Site in the DMZ zone with these roles installed : MP, SUP and DP.
    6. Re-install all the SCCM clients in the environment with the command-line so that they can be supported on both internet and intranet.
    7. Make sure internet clients are able to connect DMZ site system server via internet.
    Please let me know if I'm missing something here and let me know the practical steps to achieve this. 
    Request you not to share Microsoft technet link for the same. Please share some step-by-step practical document etc.. to achieve this.
    Thanks,
    Sam

    1. This is incorrect. You need more than a single web server cert and client cert. You need a unique server auth cert for *every* one of your systems hosting a client role like the MP, DP, and SUP. Also, you need a unique client auth cert for each and *every*
    client that may/will connect via the Internet.
    4. Standing up a whole extra site just to support IBCM is a bit overkill. It does allow you to keep your "main" primary site in mixed mode, but it does add some overhead and cost and is not technically necessary.
    6. Incorrect. You only need to reinstall clients that will be configured as "Internet-only". Intranet clients should pick up the internet facing roles via policy. You can verify this by checking locationservices.log on the clients after they are successfully
    communicating and the Internet facing roles are stood up and healthy.
    You've made no account above for the CDP or CRL checking. This is a major stumbling block for many folks.

  • Internet Based Client Management Design Question

    Hi,
    I read many articles and many forum posts about IBCM design possibilities. I want to make sure I am on the right path, so I would like to mention about what I have currently in my environment and how I will change it. Please let me know if something is wrong
    with my plannings for IBCM.
    Currently I have one SCCM2012 R2 primary site server and one database server. We dont have
    public key infrastructure at the moment , so communication is via HTTP. We dont have DMZ either. I would like to make my internal SCCM site server reachable from intranet and internet
    without installing any other site server or MP,DP,SUP point. The article below says that is possible. I will implement the scenario1 in that article.
    http://blogs.technet.com/b/configmgrteam/archive/2012/05/25/system-center-2012-configuration-manager-r-i-p-native-mode.aspx
    So, I guess
    1.I need to create
    public key infrastructure.
    2.Public DNS registration for site server's internet FQDN
    3.Firewall Settings from internet to site server
    After those 3 steps, my client will connect from intranet when they are in the office and they will also be able to connect from internet when they are outside of our network. Can you please verify whether this planning is correct or not? If you know any
    step by step IBCM implementation article that I can use , can you please give me the link?
    Yavuz Selim Atmaca

    Very high level those are indeed the right steps at this moment. Just keep in mind that this definitely is not the most secure solution.
    I created a blog post about some important configuration steps:
    http://www.petervanderwoude.nl/post/five-key-configuration-steps-for-implementing-internet-based-clients-in-configmgr-2012/
    On a side-note, if your going to build a PKI anyway, you might want to think about DirectAccess instead of Internet clients.

  • Queries regarding Internet Based Client Management (IBCM) 2012 R2

    Hi All,
    I am trying to work with IBCM, but I have few queries for which I am not able to get any proper Information from Internet. I would be really Thankful if you all can help with your advice.
    1) I will need to publish host record Internet FQDN of the Site system server, which will point to Public IP on Public DNS.
    - So If I NAT the public IP to Local SCCM server IP on firewall, will that work, or I will have to give a different Private IP?
    2) Let say I have Few workgroup machine which will be on Internet and they wont even come to office network, so in this scenario, how should I proceed.
    a. Will I be able to get Remote session of the user?
    b. Can I install SCCM client manually over the internet? if yes then what all information I will need to provide while client installation.
    c. If I use Public wild card certificate on the server, do I need to purchase Client certificate as well?
    d. If I use Internal CA certificate on the server, then I will have to install Client certificate manually on all the work group machine, I am right? can Public Certificate act as an alternative?
    e. Any other specific Port apart from 443 that need to open on firewall?
    3) Is it necessary to put the internet facing Site system server in DMZ or it is OK to use the same Site System server for Intranet and internet.
    4) Currently I have a Site System fully functional, and set to HTTP & HTTPS communication setting, For IBCM I will be moving MP and DP from HTTP to HTTPS, I want to know will there be any issue, or any other aspect that I need to take care before performing
    these steps.
    5) Currently My OS deployment, App Deployement & Software Update is working perfectly, Moving MP and DP to Https, will that effect any of the current functionality, please advise.
    Thanking in advance,
    Regards,
    Ritesh
    Thanks & Regards, Ritesh Hegde, Exchange,BPOS, FOPE, O365.

    1. Yes, the device performing the NAT will forward the traffic to the private IP of the site system. That's the whole point of NAT assuming you've configured it correctly and allowed the traffic to pass.
    2a. No, remote Control does not work for Internet based clients.
    2b. What are your expectations and what does "manually over the Internet mean"? If you are talking about client push, then technically, yes its possible, although in reality it won't work because almost everything connected on the Internet is behind
    its own NAT and firewalls that won't allow the traffic to reach the destination. Additionally, if these clients are to be Internet only (which workgroup machine must be), then they must be installed with the CCMALWAYSINF property set to true which is only
    done when manually installing the client on the system by directly initiating ccmsetup.
    2c. The certs on the clients have nothing to do with cert on the servers. All clients connecting via IBCM require their own, unique client auth cert. If you plan on purchasing these, it will get real expensive, real quick and of course remember that this
    is a recurring cost.
    2d. How else would you install any certificate? They can't magically appear on the systems particularly since they are workgroup systems.
    2e. 8531 for WSUS and 10123 for client notification.
    3. Using the same internal site system is technically fine, but I doubt your security folks would like that idea.
    4. Site Systems cannot be set to both HTTPS and HTTP. They can only be set to one or the other. Your site can accept both, but the site systems cannot. If you convert your existing/only MP and DP to HTTPS, then *all* of your clients will need their own unique
    client auth certs.
    5. Only if you don't configure things properly.

  • Internet Based Client Updates

    Hi,
    We have SCCM 2012 R2 installed, with IBCM enabled. These clients are able to switch between intranet and internet fine.
    Updates work internally and externally fine too. We only have 1 SUP configured for intranet access only, and the Internet facing server is there as a DP and MP for clients to check in and report in etc. This enables us to see if any machines have viruses
    and what software they have installed etc
    Now, the problem...
    Our mobile workforce all use aircards with a data limit. We need to be able to report on these, and for them to get updates, but only from our DPs, NOT from windows updates, which is what happens by default when a client switches to internet based.
    This is an extract from a technet article:
    New in System Center 2012 Configuration Manager, when you have a software update point that is configured to accept connections from the Internet, Configuration Manager Internet-based clients on the Internet always scan against this software update point,
    to determine which software updates are required. However, when these clients are on the Internet, they first try to download the software updates from Microsoft Update, rather than from an Internet-based distribution point. Only if this fails, will they then
    try to download the required software updates from an Internet-based distribution point. Clients that are not configured for Internet-based client management never try to download the software updates from Microsoft Update, but always use Configuration Manager
    distribution points.
    We need to able to turn this off, so they do not get updates from windows updates and consume all their data allowance.
    On our SCCM 2007 server, we simply added a SUP internally, an internet facing DP/MP and when they were on the intranet they got updates and when they were on the internet they did not as we did not distribute the packages to that DP, but got them the next
    time they were at one of our sites...
    We need to replicate this functionality.
    Can you advise how to do this in SCCM 2012?
    Many thanks

    You are welcome to file a design change request (DCR) on connect.microsoft.com.
    Are these system Win 8.1? If so, then your scenario actually shouldn't be an issue because Win 8.1 can detect metered connections and ConfigMgr client settings can be set so that they do not use metered data connections.

  • Internet Based client support with Existing PKI Environment

    Hi Team,
    I have a question.... My Environment is on SCCM 2007 environment and there is a requirement which has come-up to support internet based clients.
    My Hierarchy is : ( All in Mixed Mode )
    1 Central
    2 Primary
    5 Secondary under each Primary
    Now to support Internet based client this is what I have proposed. To add another Primary on LAN for Native Mode and  its Site System server in DMZ with MP, DP and SUP role. Only This site system server would be internet facing to support clients.
    Now to support internet based clients... I would have to move my Central from Mixed to Native mode and then New Primary server to Native mode. Please let me know if you agree with this design or you suggest another one.
    Now my company has already existing PKI environment setup on non-windows platform. I'm aware of the fact that SCCM 2007 would support version 3 of the x.509 certificate format. When I reached the PKI team they mentioned that they only sign the certificates
    and do not issue one.. They said that your application / server should generate the certificate which I can send them and they sign.
    Now I'm not able to understand how this would happen. As per my understanding SCCM cannot generate the certificate for PKI team to sign. 
    From OS perspective, via IIS we can get the certificate generated, but not sure if that is the right was to do that.
    Please suggest how can I get these certificates generated for my SCCM environment and client machines to use.
    Thanks,
    Sam

    First, you really should look at moving to ConfigMgr 2012 to make your life easier and simplify this scenario quite a bit.
    As for certs, you need more than an IIS cert, you need a unique cert for each and every managed device that could communicate via the Internet. If your PKI team cannot accommodate this, then their PKI solution is feeble and weak and you should consider implementing
    a Microsoft PKI.
    Also, it's incorrect to say that a PKI only signs certs, they do create and issue certs; these are based upon a cert request you give them which effectively contains some meta-data and the public key that will be included in the cert that they
    create, sign, and issue (honestly, not trying to throw stones, but if they truly believe that's what a PKI does, then you're never going to get what you need from them because they don't even know what they do). This is impractical to do for every managed
    client though.
    There is also a special cert type called a document signing cert that must be issued that contains a non-standard subject.
    Ultimately, the PKI must be able to issue certificates based on the requirements listed at
    http://technet.microsoft.com/en-us/library/bb680733.aspx and of course you need a method to get those certs to both the site systems hosting the roles, the site server, and the managed clients.
    If they can't give you this (which at the very least they think they can't based on your comments), then no, you won't be able to use this in-place PKI.

  • Internet Based Client Management - upgrade clients

    Hi.
    I have a customer, who wants to deploy an SCCM site and Internet Based clients. Main purpose is to patch manage the clients.
    I have one concern though - the certificate and client deployment AND the ongoing upgrade of clients.
    I believe, we will have to deploy certificates from the internal PKI and install the clients manually/scripted - right?
    How about upgrading clients when a CU is installed on the SCCM-server? Can Internet Based clients automatically upgrade or will we have to manually install every time a new client is available?
    Thanks in advance!
    /Michael

    The certificate doesn't have to be of the internal PKI it can come from anywhere as long as it can be used to authenticate the client.
    When you're dealing with Internet-only clients then yes the client needs to be manually/ scripted installed to specifically provide the client with the right information.
    Once the client is installed the normal CU packages can be used to upgrade the clients.

  • Manage System Center Endpoint Protection (SCEP) policies for Internet-based clients

    Hi,
    I've recently change my SCCM configuration in order to allow internet-based clients registered in our domain to communicate with our primary site server. The objectives were to let us manage the SCEP policies of these clients and receive alerts
    when they're infected even when they are on the road, so not connected to the local network.
    Now, everything seems to be in place; PKI certificates for server and client, the DNS is configured, firewall route too...but I still cannot update the policies of my client when it's not connected to the local network.
    I'm able to reach my primary site from my client when connected outside the network, but the policies won't update until I connect to the local network.
    Is it actually possible to manage the policies and receive alerts from internet-based clients like I'm trying to do?
    Thank you very much for your help

    It's going to come down to log checking at this point to find where the failure is happening or the connection is not happening.
    Initiate a machine policy refresh and watch the two logs noted above.
    CAS.log may also be helpful as well as locationservices.log and clientlocation.log.
    Try deploying an app as well and watch the logs.
    Also, if the client is not properly getting policy, there's no way for it to know that you disabled client CRL checking on the site.
    Jason | http://blog.configmgrftw.com
    Ok so now I see an error in clientlocation.log that might be the cause of my problem.
    [Domain joined client is in Internet]
    [Rotating internet management point, new management point is : SERVER.DOMAIN.COM ...
    [Unable to retrieve AD forest + domain membership] <- Pretty sure this is related to my issue
    I guess it's because my AD schema is not extended, is that right?
    EDIT: I thought this was the issue, but the AD schema seems to be extended already. Any idea of what could cause this error?
    EDIT: Do I need to open ports in order for my client to be able to reach the AD or something? I thought that was the MP's job once we granted him full control access on the AD. Am I wrong?
