ddns

Dynamic DNS (DDNS or DynDNS) is a method of automatically updating a name server in the Domain Name Server (DNS), often in real time, with the active DDNS configuration of its configured hostnames, addresses or other information.
The term is used to describe two different concepts. The first is "dynamic DNS updating" which refers to systems that are used to update traditional DNS records without manual editing. These mechanisms are explained in RFC 2136, and use the TSIG mechanism to provide security. The second kind of dynamic DNS permits lightweight and immediate updates often using an update client, which do not use the RFC2136 standard for updating DNS records. These clients provide a persistent addressing method for devices that change their location, configuration or IP address frequently.

    Setup DDNS Service on NAS

    Dears, Is it possible to self-host and setup a DDNS service ? A NAS-level DDNS and not a router-level DDNS. I suppose this includes a software that works in server role, on my NAS device, at my local network. What would be the benefits and costs ? Will it require first a local DNS server too ...

    Port number automatically added to DDNS url

    I have a DDNS domain name through No-IP that's working with DSM, and I can use https with LE certificates no problem. I want to use reverse proxy to stop so many ports being forwarded on my Netgear Orbi router. I'd be happy to just forward 443 to the nas and have everything coming through there...

    DDNS requirements and certificate requirements

    I only access my NAS from my internal Lan. However, I want to get a certificate so that I can connect to the admin page using SSL without getting browser prompts.

    DDNS over QuickConnect?

    Bit of a newb question but if I want to give someone their own folder on my NAS and have them access it remotely, why use DDNS and port forwarding when QuickConnect will allow them to access it?

    Very odd.. DS Video streaming is fast only when using quick connect!

    I thought some ISP throttling was going on.. check the connection on both ends, no packet loss on both ends... Both (where the synology and client locations) fast enough connections for full quality video stream without transcoding... The port for DS video is forwarded properly, it connects and...

    Setting up DDNS

    Hi all, I am looking to setup DDNS rather then using quick connect. I have a Netgear Nighthawk router and then have an Asus mesh system that runs out of the nighthawk. I believe that you have to do some port forwarding and with my limited knowledge I wasn't able to get it setup. Anyone know...

    I'm seeing an issue today whereby the DDNS settings on the DS918+ are blank (instead of the external IP being shown) and the NAS is reporting there is no external connectivity.

    Having finally managed to set up my DS218play on an Eero mesh network - DDNS, SSL certificate, https, port forwarding and so forth- I find I am only able to successfully log in using the DDNS name if I use the https port number appended after the DDNS name. Is that expected or have I missed a...
