I have two newly installed DNS-320's. My plan was to backup the local unit to a remote unit at my home(NAS to NAS). Network topology is;
Local system is on DHCP
Verizon FIOS router assigned a fixed IP address.
No ports have been opened yet.
Remote unit is DHCP
Verizon FIOS WITHOUT a fixed IP address.
Port 80 is open and forwarded. I will open 873 for rsync
Dynamic DNS is set up for this unit and is operational(I can remotely administer).
When I go to define the remote system I am required to give an IP address, DDNS name is NOT permitted! Was the DDNS simply so I can remotely administer the NAS? There is NO IP address I can supply that will have a chance of getting to the remote NAS.
What do I need to do to be able to perform remote backups? Suggestions please?
