geoff Posted December 27, 2020 Share Posted December 27, 2020 Hello, I just setup my Netduma and my Xbox is telling me i have a double NAT. I went through this guide and still showing the same. Here are my settings: ISP (Comcast) Modem is in Bridge Mode Upgraded Firmware to 3.0.179 UDNP is open and showing my Xbox IP with the proper port open Set my Xbox to have a static IP from within Netduma Put the Xbox in the DMZ Still not working Why is the WAN IP a private 172.16.x.x address on this?

Administrators Netduma Fraser Posted December 28, 2020 Administrators Share Posted December 28, 2020 Hey, welcome to the forum! The WAN Address appears like that because you've put the ISP router in bridge mode so for all intents and purposes it's behaving like a modem. There is nothing else in your setup that would be affecting ports? On the ISP router are there any options that are still available/accessible? Disable IPv6 in WAN/LAN Settings. Do you know if your ISP blocks any ports? Link to comment Share on other sites More sharing options...
geoff Posted December 29, 2020 Author Share Posted December 29, 2020 ipv6 was disabled and until the netnuma was installed i had no issues with NAT. Comcast is not blocking ports. Link to comment Share on other sites More sharing options...
