I've been facing some challenges getting my network configured as I hoped. My home setup includes a fiber connection with an integrated ONT router from CRAP, which connects my Asus RT-AC1200G+. All other devices—PCs, wireless gadgets, PS4, TV, NAS, etc.—are linked to the Asus router. Currently, everything on the CRAP side falls within the 192.168.1.X range, while my other devices are in the 192.168.2.X range. I was planning to set up a DDNS service on the Asus router since the provider's one isn't reliable, but it seems to connect technically to ddns.net, yet I can't reach it from outside the network. I'm wondering if I need to forward certain ports on the CRAP router to enable remote access. This is confusing, but my goal is to:

- Access my desktop from outside the local network
- Retrieve files from my NAS remotely
- Avoid using the CRAP router for any management tasks

Thanks for your time. Smile Your diagram skills are appreciated.

These routers are linked together in a specific order, with each device handling different routing tasks. The ASUS router is usually connected through its WAN port, which can lead to double NAT settings that often create problems for consumer devices. This setup tends to be overly complicated for the intended purpose. From the addresses provided, it seems the ASUS router is indeed linked via the WAN interface. In this configuration, client devices are unaware of CRAP’s existence and vice versa, so no traffic is routed outside the ASUS router. My recommendation is to connect the ASUS router to CRAP using a LAN port and assign an IP within the same subnet. Turn off DHCP, WiFi, or any other features you don’t need on CRAP, and enable them on the ASUS router. Configure clients to use CRAP’s address as their default gateway, ensuring packets are directed appropriately. You can still manage DDNS on the ASUS router, though it won’t handle routing. Instead, set up port forwarding on the CRAP device for network management tasks like DHCP, DNS, and DDNS. If CRAP remains at the network edge, it will still manage packet flow according to its settings, unless it’s designed as a pure gateway.

Thanks for your reply. It seems this approach doesn’t quite meet your goals. You might want to contact your ISP about getting a separate ONT so you can use your router independently.
