Xydocq Thanks to the suggestions, that actually gave me another idea that worked for me. In the UCG Ultra Gateway, I added the DNS addresses as custom DNS routing exceptions, poiting them to the internal Synology IP. This makes Unifi routes all internal requests to these DNS addresses directly to the Synology.
I have one DDNS pointing to the Photos and Audio apps from Synology (like photos.mysynologyaddress.com and audio.mysynologyadress.com, being the mysynologyadress.com a Synology DDNS). When inside my network, the address doesn’t work, I suppose because of the Double NAT. If I’m out of home, the address works - quick fix I found is starting a VPN in the device I want to use these apps while I’m at home.
Xydocq Thank you for providing these detailed instructions.
It solved most of my issues (because of double NAT and having DDNS pointing to Synology, I unable to access the address from my network without VPNing first, but the remaining services work).
The DMZ works, I just needed to change the IP range for my Ubiquiti router. It is a solution for most of the issuers, but it’s not the best solution to my problem, because I also use some services from a Synology NAS that needs an external IP access. I’m now connecting a 2nd internet service to the WAN2 to resolve this but I will move away from Sunrise as quickly as I can!!!
Daniele_Sunrise The issue is that the Fiber Box doesn’t provide an IP to the Ubiquiti router, so I cannot even use DMZ…
I recently received the Sunrise Fibre Box 3, I’ve connected it to the OTO socket and confirmed it’s working.
However, I have a Unifi network at home, with my main router being the UCG Ultra. When I connected the UCG Ultra to the Sunrise box, not devices aren’t communicating (the Ubiquiti don’t get a IP and the Sunrise box doesn’t show the UCG as a connected device). So my Sunrise finer connection is completely useless and only able to connect to the internet using my previous internet provide (still active, not fiber).
I learned that the Sunrise Fibre doesn’t allow bridge mode, so does anyone know hoe to make the devices communicate?
Thank you
