hello,

we have SCCM v2010 and I am trying to provide updates at the clients which are connected through VPN but it doenst seem to work.

I have the boundaries defined and specifically the IP range of the VPN which is 192.168.150.5 - 192.168.150.254.

when I look at my computer (connected through VPN) at the locationservices.log I see the below:


Updating portal certificates LocationServices 12/17/2020 9:13:55 AM 3892 (0x0F34)*
There are no certificates available to install LocationServices 12/17/2020 9:13:55 AM 3892 (0x0F34)

Worth to say that when on corporate network then it works like a charm.

any ideas of what I need to check/ do?

thank you

    Hi,

    Are you using PKI certificate to communicate with the MP?

    Make sure that all necessary ports are allowed on your network firewall between your VPN Clients <> Domain controller / Site server / DP / SUP etc.

    @Youssef Saad hello,

    your direction of adding the VPN IP Subnet under Active Directory Sites & Services resolved the issue of the unable to retrieve AD site membership over VPN, thank you very much,

    Hello @Youssef Saad

    no we don't use PKI certificates to communicate...

    about the ports I tried to look for that but it would help if I would know which ports should be allowed... do you know?

    Below the port list:

    80/443 - VPN Client >> MP/DP
    3268 - VPN Clients >> Gobal catalog domain controller
    80/8530 - VPN Clients >> Software Update point // If you are using Secure SUP, add 443/8531.

    thanks @Youssef Saad

    I checked at my Firewall Palo Alto and all the ports are allowed so that is not the issue...

    any other ideas?
