put in the exposed host of the fritz box 7590 my modem the ip wan of the router but anyway I have the double nat how do I avoid this thing given that in gaming

Somebody in this forum post seems to know how to do it: https://forums.whirlpool.net.au/archive/1883843

Is this a modem you bought yourself or one that came from the ISP? You might ask your ISP if they have a modem only unit that can be swapped in place for this modem/router combo unit. Over all, if you use the current modem/router combo unit and it's in router mode, all you need to do use use it's DMZ for the IP address the XR router gets from the modem.

You have a router at 192.168.178.1. What is the MFr and model# of this router with 192.168.178.1? Is this the ISP modem with built in router?

Yes check with your ISP to see what they support.

It depends if the router is giving the computer the correct static IP that you set.

So do you want to use the XR300 as an access point for your fritz box or do you want the XR300 to be the router, and the fritz box to just be a modem?

    You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.

If the isp modem can't be bridged fully, then the DMZ on the modem will be the best only solution for using the XR router with the modem/router combo. DMZ helps wtih the double NAT issue.

Modem Combo Units:
Couple of options,
1. Configure the modem for transparent bridge 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 for the IP address the NG router gets from the modem.
