sevenproxi3s Posted April 13, 2018 Share Posted April 13, 2018 hey guy i have ahd my router for 1 year now , i have it hooked up to a comcast modem (newest cisco) and i have from the beginning had it setup on a DMZ with a static ip address and had no issues until a week ago and my xbox started telling me i have a double nat and i cant party chat . i have check all of my settings on my comcast router and also have done a factory reset on BOTH and started from scratch. i have even disable the ENTIRE firewall on my comcast router and when i hook up my xbox to my comcast router i get a open NAT , but as soon as i connect to my netduma its switchs to strict and double nat ???????

RL317 Posted April 13, 2018 Share Posted April 13, 2018 I believe DMZ doesn't truly offer a full workaround. I've previously used an ISP default modem/router to R1 setup, and DMZ would not only refuse to clear the blue message box on the R1 device manager page, but the WAN IP would still be private and I'd still see two private hops at the top of any trace route. Despite the DMZ, two private IP hops indicates double NAT. I've since started using a standalone modem, or a modem/router that can use bridge or modem mode (either works), and I haven't had problems since. There's only one private hop appearing on trace routes, and the R1 has a normal, ever changing public WAN IP address. I'd recommend trying that for yourself. Look up reputable modems at a decent price for your line type (ADSL, cable, VDSL, fibre to the home etc) and try that cleaner setup. I guarantee you'll no longer have double NAT issues Is it safe to assume your Comcast modem is an all in one standard modem + router? I'd imagine so considering you mention a firewall. Yeah I had the same until I tried a TP Link router that could be placed into bridge mode so the R1 would be handling all of the "routery" stuff. Now I'm using a simple modem only and it works even better. Link to comment Share on other sites More sharing options...

The advice above is great - even if you get an open NAT wired directly to your modem but a closed NAT wired to the Netduma, it can still be the modem causing the issue. If you have UPnP enabled on the Netduma and Port Forwarding disabled (and you have tried manually port forwarding as an alternative) there's no reason why you should have a closed NAT unless your modem is to blame. Do you have multiple consoles displaying a closed NAT? Link to comment Share on other sites More sharing options...
sevenproxi3s Posted April 13, 2018 Author Share Posted April 13, 2018 @ netduma jack i have a PS4 connected to my netduma and it says : NAT type 2 which is good ... i also dont think my issue is the comcast router ( yes its a modem + router ) bc i can connect straight to it and boom i have open nat ... i have COMPLETLY disabled the firewall on my comcast router which in the past has worked with zero problems but now just out of the blue i have a double nat issue .

sevenproxi3s Posted April 13, 2018 Author Share Posted April 13, 2018 just to add more information here , my comcast router supports IPV6 and it works when i connect straight to my comcast .... i have ALL ipv6 stuff checked and enable on the netduma but it will not issue a ipv6 address to my Xbox??/?? if this would work my problems would be sloved Link to comment Share on other sites More sharing options...
sevenproxi3s Posted April 13, 2018 Author Share Posted April 13, 2018 so basically what i can see on the IPV6 is that it just doesnt work on the netduma .... netduma guys really need to take this option off bc its just a lie .... if it actually worked the xbox would pull a ipv6 adress when it was enabled on the router .....

I'm getting an IPv6 through the R1 to my phone right now. Can't say the same for my PS4 but that doesn't have full support for it yet. I can't comment on the Xbox One though as I don't have one.

e38BimmerFN Posted April 14, 2018 Share Posted April 14, 2018 IPv6 works on the R1 if our ISP modem is a stand alone modem and your ISP services native IPv6 thru the modem. If your modem has a built in router, then it's possible IPv6 from the ISP may not get to the R1 router. DMZ should be used if modems have a built in router for the R1. DMZ helps in double NAT conditions. Stand alone modems are preferred when using the R1 or any gaming router. http://badmodems.com/Forum/viewtopic.php?f=3&t=65000 Link to comment Share on other sites More sharing options...

Administrators Netduma Admin Posted August 11, 2018 Administrators Share Posted August 11, 2018 It's probably best just to start over again. Could you do this please: Delete all port forwarding rules, DMZ rules etc you have currently setup Enable UPNP on your Netduma R1 Put your comcast router into 'Bridge Mode' or 'Modem Mode' Now please retest and see if it's ok.

David824 Posted August 12, 2018 Share Posted August 12, 2018 So if I have a stand alone modem I should keep my ipv6 enable? I have a stand alone but have it disabled on my r1... Well it make a difference keeping it on or off with playing online? Link to comment Share on other sites More sharing options...

I have a stand alone but have it disabled on my r1... Well it make a difference keeping it on or off with playing online? IPv6 makes zero difference to gaming. Router / ISP companies will tell you otherwise, but it's all marketing and false information. IPv6 literally just changes your IP address to a different format. It means if you're not technically on an IPv6 connection, you'll get slower speeds if you enable IPv6. That's why we recommend keeping it disabled. If you are on IPv6 you could equally leave it disabled - it can be a struggle to get it to work properly with your devices. If you're certain you're on an IPv6 connection and you really want it to work out for whatever reason, try enabling it and test whether your IP addresses have changed.

David824 Posted August 13, 2018 Share Posted August 13, 2018 Ok...I've always read that online gaming isn't even set for ipv6.. Which is why I assumed it didn't matter if it was on or not Link to comment Share on other sites More sharing options...

Which is why I assumed it didn't matter if it was on or not Exactly - PS4 doesn't even support IPv6. You know a feature is pointless when one of the leading consoles completely disregards it. Then Xbox went and marketed IPv6 like it's a great gaming feature, simply because PS4 didn't have it. Talk about clutching at straws! You're good to go without IPv6, don't worry about it Link to comment Share on other sites More sharing options...

Savage burn! LOL I think the idea is that when it's fully up and running, routing should be improved because packets won't need to go through so many hops, and processing will be improved with its simplified packet headers. But of course if next to nobody is using it and services are slow to transfer over there would likely be a degradation in performance if there's any difference at all. I remember using a site that runs IPv4 and IPv6 ping tests simultaneously and while IPv4 was fast and stable, IPv6 gave me up to four times more latency and it was all over the place ¯\_(ツ)_/¯ Link to comment Share on other sites More sharing options...

Yeah right now I think it's just a gimmick they're milking for sales. I have an XB1 now rather than just a PS4 so I could actually run some tests on the diagnostics page and in game to see if there's any difference. After all of the settings tweaking I did last year to no avail, I can safely say I have a good resistance to the placebo effect LOL Link to comment Share on other sites More sharing options...
