Access Synology NAS externally



  • I have a Synology NAS connected to my pfSense firewall.

    I have enabled DDNS on the Synology which gives me a url to access my device, however when I visit that URL it takes me to the pfSense GUI.

    What do I have to do to get it to go to the Synology?

    Hit it from the actual outside.. Don't try and nat reflect in from your DDNS..

    Why do you want/need this?  If your remote and need to access your synology - just vpn in your network on pfsense openvpn remote access setup.  I have a ds918+ and see zero use for their connectivity stuff.  That being said be more than happy to help you getting yours working.. Are you talking about their ezconnect when you state you setup ddns?

    Can fire it up and give you some screenshots both on the syn and pfsense if need to show you how to access it.. But again keep in mind from a security standpoint anything you open up to the public should be considered risky.

    Its under External Access in DSM. Have a DDNS set up as with a synology.me hotsname. Mainly just so I can tell at a glance if its connected to the network and the network is still up.

    That is just typical ddns type service.. That would point a fqdn at your public IP.  Pfsense has the same sort of feature.

    If you want to actually access anything from behind pfsense from the internet you would need to port forward to your nas IP on pfsense.

    So here I fired that up.. If I want to check status of the nas I can just login into the synology account and look under my devices.  Shows Green.. The way I read that you would get an email if it goes down, etc.

    Tell at a glance from where exactly??  hitting whatever.synology.me from a device on your lan would just send you to your wan IP.. What that access would depend on what you have setup on pfsense.  Out of the box yeah it would just hit your wan IP - which would be your gui out of the box unless you setup some sort of nat reflection, etc.
