I have a problem with the connection, while I am playing FPS game on PC. There is excessive lag which is affecting me a lot in my performance. I am playing with Ethernet cable connected, I tried to create a new custom portforwarding, I have tried to disable the firewall, then I have tried to switch to Modem mode, and I also tried to change my computer options but it is still lagging. I find out on a website that I need a NAT Type Open for my game. (1)But do I have one and how can I find out the NAT Type that I am using ? (2)How can I switch/create a NAT Type Open in my router? (3) I have a list of number for TCP and UDP, which one should I use?
