    DNS Relay using Container Manager

    I'm looking to see if anyone has configured a DNS relay using their Synology. DNSFilter offers a Docker container, which I would believe could be run in Container Manager. Curious if others have any experience in doing this, and if so, would be willing to help a newb set one up.

    So after much trial and error, I managed to set up three WordPress container sites on my NAS, with reverse proxy for each so the sites are accessible from outside my network at DOMAIN1.com, DOMAIN2.com and DOMAIN3.com. Unfortunately, I cannot connect to those URLs from within my network, only...

    I've got an RT6600ax router for my home network, with a DS720+ NAS connected for file storage. I've got a Windows desktop connected by ethernet, and a phone connected by wifi. I'll preface this by saying I am in no way a network expert, and even the words "DNS" fill me with dread. That said...

    Unqualified (local) DNS lookup

    I'm wondering if it's possible to configure Synology DNS to provide a default domain when an unqualified name is sent. I can't see anything in the GUI or documentation that talks about this. My old system uses dnsmasq as the DNS server, and when set with the --domain option, this will only...

    DSM 7.0 support for dhcp leases in dns records

    It appears that historically DSM lacks support for serving host names from DHCP leases in DNS queries, with users requiring such functionality forced to rely on third-party backdoor solutions. Is this limitation resolved in DSM 7? Will the same solutions work as before? What is the safest...
