SCCM client stuck downloading 0% when connected via VPN – IP Subnet vs IP Range SCCM boundary.
Does your organization use VPN where a remote client no longer act as a network but as a standalone host which communicates on an interface where it has been assigned a subnet mask 255.255.255.255? This mask refers directly to the host. It is sometimes called a host route because there is no network address, just the host address.
When your SCCM administrator uses a “IP Subnet” based boundary assignment like for example “10.34.56.0” or “10.23.56.0” none of those boundaries will include a VPN end point with a mask “255.255.255.255”.
Most F5 VPN Edge clients receive an IP address with a mask “255.255.255.255”. Details regarding F5 VPN can be found here
At osd365 we always use ‘IP Address Ranges’ for VPN boundaries. When using ‘IP Address Ranges’, irrespective of the mask the assigned IP address will be used to check if the client is within an SCCM Boundary.
This solution helps solve problems like.
- Stuck ‘Downloading 0%’
- No distribution point assigned.
- Downloading from 0 content servers.
The IP ranges can also be set using AD sites and services.
