 ## Filer Proxy 
 
-By default, filer.sync will upload files directly on master and volumes, it uses IP configured in the filer. These IPs could not be accessible to the filer.sync cause of network configuration (for example cluster1 and cluster2 are on different hosting providers). In this case, it could be useful to use the filerProxy option to make filer.sync does all the transfers through the filer. In order to enable this option `-a.filerProxy` or/and `-b.filerProxy` can be added to the `weed filer.sync` cli.
