WD PR2100 NAS on Double NAT
« on: April 02, 2020, 06:09:58 AM »


my connection is like this. ISP modem&router Innbox F60 (192.168.64.xx), then on WAN connected DIR 882 and on LAN (192.168.0.xx) of the router WD NAS.
Everything works when I am connected directly to my router.

The problem is when I want to connect to my cloud through cellular data. It doesnt work because of  double nat they say. Is there a way to virtualy put NAS to network from ISP. Or maybe some other option?

Thanks for any suggestion...

If you have the option from your ISP to switch your FTTH gateway to "bridge mode" without the router functions activated that would be your best option . You would then just create the PPPoE session on your router and you wouldn't have any other issues (I assume PPPoE connection since that is mostly what's used in conjunction with ONT FTTH service).
If however that is not possible there are 2 other workarounds :
1. make all necessary port forward from the ISP's router to your router's WAN IP ( 192.168.64.x not the LAN 192.168.0.x subnet ) ; after that make normal port forwarding rules in your DIR 882 config portal to you WD NAS's IP  as you would normally .
2. transform your DIR 882 router into a makeshift AP ( http://forums.dlink.com/index.php?topic=40856.0 ).After turning the router into an AP you must create all necessary port forwards in the Innbox modem/router to the new WD NAS IP ( now all clients within your home will be on the same 192.168.64.x subnet leased from the DHCP server of the Innbox modem ) . The benefit with this option is that you would gain not having a double NAT to worry with and would also possibly gain some switch ports ( now the active Eth ports on the Innbox modem/router and the new DIR 882 AP would be on the same logical network and you could use them all )
