    Port-Symmetric Nat: Strict. How to open?


    Im currently unable to play online and having trouble connecting to games because of my nat. How do i get around this? I tried checking with the bumper/trigger trick microsoft says and it told me my nat was behind a UPnP Port Symmetric NAT: Strict. How do
    i get it open so that i can play? Im currently using CZee Versiworks internet and using a Netgear WNDR3400v3 connected directly to the router (Hardlined) Any help would be appreciated.

    :)

    Who is your ISP? (Internet Service Provider): Cable ONe (Military)

    Modem brand & model number: Not sure, live in dorms and just have a router set up that links into the wall via rj-45.

    Router brand & model number: Netgear 3400v3

    Is your Xbox One connected via wired or wireless?: Wired

    Things you have tried (UPnP? Manual port forwarding? DMZ? Wired Xbox One directly to modem?): ive tried UPnP and Manual Port forwarding via the portforwarding.com guide.

    Is UPnP Enabled on your router? yes

    Do you have a NAT error? If so, what is your NAT type? no error message but its strict right now.

    Any Error Codes you encounter: none

    Do you get a Teredo IP error? no

    Does the WAN/Internet IP (NOT the LAN IP!) listed in your router's web interface match the IP reported by
    Trace My IP | IP Address Tracker | IP Tracer | Computer Hardware IP Visitor Location ?: not sure how to look, my router configures the ip from ISP dynamically. i HAVE internet on the xbox, just wont let me join games online for titanfall.

    The last question is critical. The web interface of your router (same as where you go to forward ports) should have a status or overview page that reports its Internet/WAN IP. Given your setup, I'm fairly certain that IP will not match the public IP reported
    by the tracemyip page, but you need to verify.

    found my internet ip i believe, but its not what the site told me it was. its still a 192.168 address but its not the routers default subnet mask and instead is a 180 in the third octet. so i believe thats the IP address im looking for.

    Port-Symmetric Nat: Strict. How to open?

    Yes, and it is as I thought. That is a private class IP, which means your Xbox has at least 2 layers of NAT (double NAT) between it and the Internet--the first being your Netgear and the second being a NAT router at your ISP and, thus, out of your control.
    You cannot get open NAT in a double NAT situation unless you take special steps--steps that require access to the upstream router (your ISP's), which access you don't have. I explain this problem more here:

    forums.xbox.com/.../1722039.aspx

    About all you can do is try wiring your Xbox One directly to the ethernet port on the wall (remove the router). If you still get strict NAT, which is likely, then that is the best you can get without cooperation from your ISP, which is probably unlikely.

  10. TRY THIS: go to network setting and go to advanced settings and set your dns servers to manual and put only one number per box for the primary.. ie [4].[2].[2].[2]

    then on the secondary do [8].[8].[8].[8]

    you do not have to put the dots as they will be in red between the boxes.

    then try to play the game.. if you still come up with issues then try deleting and redownloading after power cycling the console.. (turn off and remove power cord from back of console and tapping the power button 3 times then plugging back in, COUNTING TO
    10 then turning back on.. make sure the power on switch is lit up.) After a power cycle expect it to take longer to boot up.
