Offline development environment -local dev VM without internet connection

(0) ShareShare
ReportReport
Posted on by 365

Hello Community members

I have a weird requirement. I have a customer with very restricted network policy.

The customer plan to use Dynamics 365 FO on-premise and they will have development environment locally hosted.

For now, We want to run a development environment with limited internet connection.

By limited, I mean there is no direct internet connection on the development machine. We can request them to open some URLs and ports to communicate with internet with a proper justification. they can open only specific sites after studying the justification with narrow possibility.

My question is, can we have any list of sites/ports which if enabled, can make the development environment work properly?

I can find some links on on-premise troubleshoot guide.

lcsapi.lcs.dynamics.com:443

login.windows.net:443

uswelcs1lcm.queue.core.windows.net:443

www.office.com:443

login.microsoftonline.com:443

dc.services.visualstudio.com:443

uswelcs1lcm.blob.core.windows.net:443

uswedpl1catalog.blob.core.windows.net:443



I am not sure if there is any other list to be accommodated for proper operation of development environment.

Any ideas or advises.

    Hi Abdul Aziz,

    The requirement seems to be okay. Organizations do have strict IT policies for accessing websites.

    Though you might not find a particular list of websites for Local development environment.

    I can suggest you to do it progressively. Which means that you can get the IT team to allow access to the IPs which you know for sure. Then with time and development/deployment process, you will come across other websites as well.

    You may then prepare the list of those websites and get the unblocked by your IT team.

    Hi Abdul,

    You can start with the list you provided yourself. The most important would be the authentication to login on Visual Studio and Dynamics 365. Also a connection to DevOps source control would be required.

    You can use e.g. Fiddler to find out about other communication.

    Many thanks for your advises.

    For now, I have managed to run the VM by requesting whitelisting of below URLs

    mscrl.microsoft.com

    *.verisign.com

    *.entrust.net

    *.management.core.windows.net

    *.graph.windows.net

    secure.aadcdn.microsoftonline-p.com

    *.microsoftonline.com

    *.crl3.digicert.com

    *.crl4.digicert.com

    *.ocsp.digicert.com

    *.www.d-trust.net

    *.root-c3-ca2-2009.ocsp.d-trust.net

    *.oneocsp.microsoft.com

    *.ocsp.msocsp.com

    *.crl.microsoft.com

    I found them on MS docs related to troubleshooting AAD connectivity issues.

    The client is not happy with that and need justification for each of the sites.

    Thank you all once again.

    Hi Abdul,

    What about forwarding the MS docs page to the customer? Do they need a justification if it is verified and published on Microsoft Docs? The majority of the sites are Microsoft services or related to certificate authorities.
