Hi,
I recently moved to a GL iNet router for NextDNS support.
I am using a Synology NAS since about 2 years and have previously setup a DDNS to access my NAS from outside my home networks.
The problem I now have with my new router is that this ddns now resolves in the Router console and not the Synology NAS. I have read something that this might be due to the router using the same port for the console as the Synology but I don’t know how to proceed.
The default Synology login to DSM is TCP 5000 for http and TCP 5001 for https (install a certificate). Various services use different ports.
Personally, I would not open ports directly from the Internet to my Synology NAS. I would prefer to set up a VPN server for remote access to my LAN.
Before moving to the GL.iNet router, did you have a different router with the Synology NAS connected to one of its LAN ports? If so, it must have had port forwarding set up that you may be able to copy from.
I do not work for and I do not have formal association with GL.iNet
