NAT Issue in COD Black Ops 4 PC (PTCL VDSL 25 Mbps) #Ready-to-Pay

AOA,

I'm facing NAT issue in COD Black Ops 4 and I'm unable to join any looby. I have opened all the ports as suggested, but all in vain. I have also set my IP as static IP in LAN (DHCP). See the screenshots. I'm ready to pay the person who can solve the issue.

why you have put your PC in DMZ? don't do that!

I removed my IP from DMZ, nothing happened.

Probably PTA WMS causing issues. Its so bs, even I have open nat type yet Vivox voice chat doesn't work in-game. PTA is creating such a bloody mess.

Is UPnP enabled on your modem?

Any solutions? Does PureVPN open port work?

Yes

Then remove all these conflicting NAT / firewall rules you've created in the modem.

Leave UPnP enabled, and check if there's a Windows firewall rule for Black Ops 4 on your PC. That's usually what creates a request for UPnP to open a specific port. If there isn't a rule or you didn't accept the Windows firewall prompt when the game was first launched, then Windows will block inbound connections for BO4.
