DS220+ not working using TPLINK ER605 and ASUS TUF AX4200

[nelvash606]

Hello friends,

I recently changed my network setup, I added TPLINK ER605 for dual WAN feature and load balancing, my NAS is connected to the asus router via the dual link aggregated ports, then asus router connected to the tplink er605 where my ISP1 & ISP 2 are connected, my PC meanwhile is connected to my asus router.

Unfortunately, using this setup my NAS cannot be detected anymore, I think I need to setup port forwarding on my ASUS router but not quite sure with the settings I need to input.

Hope you can suggest a solution, thank you in advance.

From what you describe it sounds that you have two layers of routers between the Internet and your private LAN.

I'm not sure what you mean by "my NAS cannot be detected anymore" because you don't say from where, by what, nor how you are trying to 'detect' it.

hi thanks for the reply, for the NAS, I am trying to connect via the synology assistant, also the drive is not updating the 2 way update and backup, I tried to restart the NAS itself, it will connect but will disconnect later, it seems like it tries to connect itself but hard to push through

So you mean you are doing this from your PC to the NAS and both are on the private LAN behind the Asus router?

I don't use Synology Assistant someone else may be able to help on that. By 'the drive' do you mean Synology Drive and the PC client cannot access the server on the NAS? How have you setup the connection in Synology Drive client... using the NAS's LAN IP, a DDNS server name, or QuickConnect name?

Another thing: the TP-Link router is now connected to the Internet with its LAN connection to the the WAN port of the Asus router? Have you configured a different private IP subnet between the two routers, and how have you assigned IP addresses on it?

Yes, I access it with my PC

I already did setup it before and working fine, just recently I changed router and added the tplink er605 to manage dual ISP setup

The 2 ISP's are connected to the tplink and the asus router connected to tplink and NAS connected to asus router together with my PC, not sure if that how it should goes, I will look at the IP assigment though
