metalink not returning URL for private mirror

Hello, 

Our organization is running high number of linux machines and to save bandwidth and
resources, we've created private mirror to redirect all our machines via metalink to
it. 
We sync data every 2 hours with quick-fedora-mirror and then run report_mirror to inform
upstream about our state. We only mirror part of the EPEL tree, could that be the reason,
why metalink is not returning our URL to our restricted ranges? If yes, how can we
override all that without mirroring entire EPEL tree? 

Thanks
