If you want to keep Deco parental controls, that would mean running Deco in router mode. With that in mind, I am going to simplify your picture, leaving only relevant to your quesiton parts. This is what you want to have:

 

 

With this setup, these are answers to your questions.

 

1. Keep the NAS fixed address

 

As it is now obvious from the picture, Router 2 (a.k.a. Main Deco) should be providing fixed IP address to NAS, not Router 1. You can configure fixed IP address for NAS on Deco, by following this document: How to configure Address Reservation with Deco?

 

2. Pass through the ports through deco to the NAS

 

You can set port forwarding on Main Deco (a.k.a. Router 2). This is how: How to set up Port Forwarding feature on the Deco?

 

3. Access to NAS from the Internet

 

I am assuming you asked for port forwarding, because you need access to NAS from the Internet. If not, you are all set.

 

If you do need access to NAS from the Internet, you have Router 1 standing between Internet and Main Deco. You have multiple options to try, each should work:

 

- Configure Router 1 in bridge mode;

- Set port forwarding on Router 1 to Router 2 (to Main Deco);

- Put Router 2 (Main Deco) into DMZ of Router 1.

 

Also, for last two options to work reliably, you may wish to set static IP address for Main Deco on Router 1.

Thanks for the input. Your setup means that i will have to change the ip of the NAS, and that can be troublesome if missconfigured and i would rather not do that.

 

Or I can change the dhcp range on router 1 and use it on router 2. that might actually work.

Or perhaps only change the mask to a B address scope as in 255.255.0.0 on router 1, then I might be able to set 192.168.0.1 on router 2. 192.168.0.1 address range is used by router 1 today. Thanks.

 

I want to keep the adress of the nas intact =)

Hello

 

Kind a fun to have 3 dhcp servers where 2 of them work together.

 

So for now i can access my nas from the deco network even if the nas is on another network as in pic 1(address from old router). And I have been able to add a second address to the NAS. =)

 

So if i shutdown the dhcp function it will work even better. And test to see if the old router can act as a switch.

Also need to check if the router 1 can be bridged and still act as a switch.

 

 

It has been working flawless. I have 2 nics in my nas, so I can access it from diffrent netowrks. But suddenly it stopped working. I can only access NAS from the deco address on while the NAS has an adress from router 1. So strange. Its like NAS wont take an dhcp address from the deco..or even a fixed address from deco. I switched the nic´s mac addresses and it set it to accept a dhcp adreess, seems it will only take it from the router 1. ten back to a fixed adress, still no luck. So I repeat, i have an adress from deco 192.168.68.7 on my pc mask /22. I can by wifi reach my nas with an adress of 192.168.0.68 mask 24. If i set an fixed address on my nas as 192.168.68.78 i cant access it. It dont show up in the deco app as before. No sure if deco has been updated. I know the nics are working. .
