Calling back with empty distribution points list : Local DP vs Remote DP

Question

Hi all,
I am an issue getting remote offices to pull packages (A task sequence) from their onsite DP. They keep pulling from the main DP in the datacenter.
How do I ensure the mainDP is not considured 'LOCAL' but it is 'REMOTE' and the local office DP is 'LOCAL'?
Here is my setup:
SCCM 2012 with DP / MP set in Datacenter: mainDP
3 Offices up the country with local DP Server: OfficeDP1 / OfficeDP2 / OfficeDP3 (green under monitoring and my packages show as verified content) 
SCCM Boundaries set via "AD Site". This matches our AD Structure. In AD Sites and Services, each site has a unique IPv4 addressing (AD Address Prefix: Office1 - 192.168.100.0/25 & Office 2 - 192.168.101.0/25 etc)
Each SCCM Boundary has a boundary group that reflects the local office
The locationservices file on an office PC has:
Current AD Site of machine is Office1
Calling back with the following distribution points
Distribution Point='http://mainDP/SMS_DP_SMSPKG$/PR10005D', Locality='LOCAL', DPType='SERVER', Version='7804', Capabilities='<Capabilities SchemaVersion="1.0"><Property Name="SSLState" Value="0"/></Capabilities>',
Signature='http://mainDP/SMS_DP_SMSSIG$/PR10005D', ForestTrust='TRUE',
I would expect it to say http://Office1DP/SMS_DP_SMSPKG$/PR10005D
This is how I configured my separate packages / programs:
Package A and Package B:
Data Source Tab: disabled Binary diff replication
Data Access Tab: nothing ticked
Distribution Settings: ticked - distribute the content for this package to pref dist points
Program 1 and 2 respective config:
Advanced tab: ticked - Allow this program to be installed...deployed
This is settings when the TS deployed agaisnt Device Collection
Distribution Points Tab: Nothing ticked (no fallback configured nor use remote distribution point)
Deployment options dropdown: Download all content locally before starting task sequence
This is the CAS.log file

and then the CTM log file:

ContentTransferManager 16/12/2013 17:42:15

Nothing points to the local officeDP which has the content successfully distributed and verified against it.
Help
Thanks

This may not be the answer you're looking for since you're doing boundaries differently.
This is how I have it setup and it works perfect.
1)  Do ip ranges for all boundaries
2)  Assign each boundary to a boundary group
3)  Add the remote dp as the site server in the boundary group
4)  Also make sure the main local dp also has a boundary group with all the ip ranges that don't have a remote dp.
I believe when you download something from software center, you can check the following log to see what download locations it finds.
