Updates not downloading or installing on clients

[kesh]

I have an issue with my CB setup. I have a single MP and 4 different sites. I have 4 boundary groups with a single DP in each group. MY MP also has the DP role as there are servers in the same site as my MP that require updates downloaded to them - those are working fine. The other servers only have the DP roles setup. 

My issue is that updates are being deployed to my remote sites. They only download and install if I add my MP into my boundary group however that is defeating the purpose as clients then access updates over the WAN. Once I remove it, I dont get the deployments. Content has been deployed to all DP's

How are you boundaries set up? AD sites? Subnet? Are the boundaries associated to the correct boundary group?
