Help configuring 3820 and net net central for reporting.

I have followed the doco for this but it is still not working. The SBCs talk to the NNCentral for traps ans such but they seem that they cannot for the reporting ftp/sftp. I can SFTP to the nncentral from my desktop just fine.

Here is my config on the SBC's

collect

                sample-interval                         5

                push-interval                           15

                boot-state                              enabled

                start-time                              now

                end-time                                2014-03-11-16:53:33

                red-collect-state                       disabled

                red-max-trans                           1000

                red-sync-start-time                     5000

                red-sync-comp-time                      1000

                push-receiver

                        address                                 x.x.x.210

                        user-name                               nncentral
