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 ...
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.

Try option #1 first, if not, #2...
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.

Depending 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.
Hi,
Thanks for your help so far.
So I have done a tracert (via CMD) and its funny because I can get route traces for sites, such as the BBC or CNN, but cannot get my NAS domain name address resolved. It's as if DNS is not recognising my domain name. However, if I try to access my domain name from outside my LAN, I can get through.
Any thoughts? Is it a certificate problem ever since I added the Netgear router in?
Thanks
If your trying to get responced back thru the router, not sure if this model supports loop back which is sometimes needed when resolving from the LAN to WAN back to LAN side.
If the R series router is in the ISP modems DMZ, this should help alleviate some of the double NAT issues however I've see some ISP modems not do DMZ or IP passthru correctly.
You might try the NAS connected to the ISP modem and see if it works there with out the R series router online...
