@terziyski I have tried to use DMZ and put my ip address but it doesn't work in terms off open all the ports. with the virtual server which service type do I use?

And how can I open all the ports at once?

@terziyski Hi, sorry I'm new to this. What is the service type and for NAT forwarding do I need enable DMZ? And which ip address?

@terziyski where can I open those ports in the TP-Link setting?

Hi everyone, I have tried to open up my ports on the router VR2100 but it worked for some games like GTA however, Call of Duty still saying the NAT type is strict. Is anyone able to fix this?
