I recently bought a Synology DS412+ and am trying to set it up for remote access. Currently I'm trying to be able to access the DSM tool.
My home setup is as follows:
- The internet connects to a Sagem Webr@cer (VDSL modem + router). This router (192.168.1.1) operates in the 192.168.1.x range.
- Via cable, a second router Linksys E1000 is connected. This router (192.168.2.2) operates in the 192.168.2.x range.
- The NAS is linked by cable (twice) to this router, and has the fixed IP addresses 192.168.2.18 and 192.168.2.19. I'm trying to set up the remote connection via the 192.168.2.19 address.
I registered a xxxxx.synology.me DDNS address, and it correctly resolves to my home IP address. I forced a refresh of my IP, and the DDNS was changed within minutes. When I enter either the IP or DDNS address in my browser bar, the page does not load. However, when I open this URL from within my home network, I get my top router (192.168.1.1) configuration page. If I open that page up to remote access, I also get this config page when accessing from remote (which is a bad idea, but it proves that the DDNS is not at fault here).
So I assume there is an issue with my port forwarding on the top router. However, I am unsure how to correctly set up port forwarding between different routers. The ports I'm trying to forward are 5000, 5001 and 80.
Am I supposed to forward the ports to the second router (which then subsequently forwards the port to the NAS), or can I configure the top router to directly forward the port to the NAS? I already tried both and neither worked, but maybe I'm missing something.
I tried setting it up via DSM and manually, but neither method worked for me. I think I'm missing some key piece of knowledge about a multi-router setup to correctly set this up.
Can anyone shed some light on the situation? If something is unclear please feel free to ask.
