Hi, I did try this but it made no difference. I opened tcp/873 from the public IP of the hosted DSS and pointed it to the internal address of the source DSS. I am a Cisco Certified Network Professional, so I am pretty sure that I know how to this.

I would be grateful if you could explain why the destination DSS needs to initiate a connection to the source DSS when it is the source DSS that is pushing data to the hosted DSS?

As also stated, I already use rsync for backup of linux internal servers to hosted servers without any problems.

Thanks,

Martin
