R8000 NAT/port forwarding issue
Hi,
I just got the R8000 and it sits between my service provider modem/router and my Synology NAS.
I have configured the R8000 to be on a different subnet (192.168.1.1) to my broadband provider (EE Smarthub) (192.168.0.1). The EE Smarthub no longer has DHCP enabled nor am I using its WiFi. I have also configured port forwardings on both routers to get remote access to my Synology.
The problem: I can access my Synology NAS from external network using the DDNS configured domain, but cannot do the same on the internal LAN. I can however access it locally by using its local network IP address (192.168.1.X).
Can anyone please help?
Many thanks
Bobby

This would be a double NAT condition which isn't recommended.

Couple of options,
1. Configure the modem for transparent bridge or modem only mode. Then use the NG router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.
2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ/ExposedHost or IP Pass-Through for the IP address the NG router gets from the modem.
3. Or disable all wifi radios on the modem and connect the NG router to the modem, LAN to LAN configure AP mode on the NG router.

- Hi,
Thank you very much for your suggestions. I have in fact configured as option 2 as you suggested because the modem/router does not allow bridge mode. I am still however having the issue I mentioned.
ThanksDepending upon now well the DMZ or IP pass thru is on the ISP Modem, you may still encounter the double NAT issue.
You may need to put the R8000 in to AP mode and let the ISP modem handle the NAT.
