[V4K4RUL]

I have moderate nat in cod and I want to change it to open,I tried port forward dmz upnp on,also I have a ont ,do I need to do the same? I'm ineducated here,my routers setup is like this ISP ROUTER>NETDUMA R2,im on the 4.0 version if that helps

How have you set up the ISP router to ensure all traffic flows to the R2? E.g. R2 in its DMZ, modem/bridge mode

Also what platform are you playing on?

Hi! I'm on PC,the isp modem is not on bridge mode im using the wifi on it for the house,since it's better,or I don't know how to set it up properly in duma,anyways I set the dumaos on dmz from my isp router,i'll enable dmz for dumaos settings for it too

Just to double check, make sure the R2 WAN IP is in the DMZ on the ISP router. Do not put your PC in the DMZ on the R2, you don't need to touch the DMZ in R2 settings.

Disable the Geo-Filter, reboot your PC then check your NAT type, is it open? If so re-enable the filter and you can ignore the NAT reading going forward.

It is still moderate nat,should I set the wan from dhcp to static ip and if yes,could you help me on how to do it?
