    Comcast Xfinity internet nat issue with xbox one


    Comcast does not support the xbox one ports i called them they connected to my pc witch was not necessary they charged me $150 for them opining the ports on the modem that is not accessible by anyone but Comcast support ... the nat was open for a short period
    of time until the modem reset from a power outage... is there any way to avoid paying another $150 ? i don't know but the only thing i can think of is Xbox/Microsoft gets in contact with comcast so they can have them open the oprts for the xbox one... the
    xbox one nat check tells me : " your network is behind a port preserving port symmetric nat " when its the only thing hooked up to the modem and like i said i can not access the modem to change the port settings only a Comcast support person can...

    :)

    lol it dont matter what the model of the modem is i cant change anything on it its restricted access so it really dont matter the modem is LOCKED the only thing i can do is plug it in and hope it connects to the internet when i unplug it.... i can not change
    anything on it it is restricted the modem has only one thing when you connect to it and it tells you that you can not access the modem you do not have permissions to access this device

    It does matter. If it is just a modem (not a gateway), then it is not doing NAT at all, and your problem lies elsewhere. If it is a gateway, which seems likely, and if there is no way for the user to access its port forwarding settings (again, need model
    to verify), then my suggestion is to buy your own modem-only device (such as the Motorola 6141) and your own router. Both can be had for less than $150 you already paid Comcast and are better and in the long run cheaper than renting the gateway from Comcast.

    Please post the make and model of your "modem" (which sounds like it is actually a gateway--i.e. modem+router) and any other router that you have connected behind it.
