To find what IP you have you need to go to Control Panel > Network and Internet > Network and Sharing Centre > click on Change Adapter settings link in the left side of the window > Right click your internet adapter and click on status. IP you are looking for is the IP of your computer or console on the LAN. In it you can Add rules that setup port you want to forward (or a whole range of ports) and to what IP you want to forward traffic to. Next you need to find a settings page in your router that lets you setup something that is usually called “Virtual Servers”.

It should ask you for a username and password (usually default values are username: admin password: admin but it depends on the manufacturer and you should check your router manual). Most routers or internet modems can be accessed via your web browser by typing one of the following addresses: 192.168.0.1, 10.0.0.1, 192.168.1.1. What does this mean? You need to setup your router so that all network traffic from the internet on the ports listed above is sent directly to your computer. (thanks to kilyan in the comments for pointing this out) There should be no need to do this, but if everything else fails try opening these as well. These are ports for internet page communication and safe https communication. NOTE: Ubisoft recommends you open ports 80 and 443, but that is quite unsafe. For XBOX Live users you might want to open port 3074 (try UDP, but if that doesn’t work add TCP as well) (thanks to Alex in comments for pointing this out).For Honor requires the following ports to be opened to function properly:

You might have to open the same ports for your XBOX One an PS4 as well, but the guide was written with PC users in mind. Opening Router Ports to have For Honor NAT OpenNOTE: This is taking into account PC version of the game. If the top result begins with .x or 10.0.x.x or 172.16.x.x than your internet provider has protections on its side and nothing you do on your router will help). (to see if you have a public IP assigned or private, which is a sign of NAT enabled on your internet provider, type into google “What is my IP”. If none of these work you probably have NAT enabled at your internet provider and most likely you won’t be able to do anything about your setup. IF that does not work try seeing if disabling your firewall helps.
IF that does not work try setting up DMZ. If that does not work, try steps bellow to open up ports for the game on your router. Reset the router after the change and start the game anew.
UPDATE: Security-wise the best thing for you to do would be to enable uPNP on your router first. With hopes that this is not the case I will go into setting up your internet router for port forwarding first, because when I did that I managed to get NAT Open status. There also might be a possibility that there is nothing you can do and that your internet provider is doing some port blocking that you can’t avoid. I recommend you do one change first, then check if the NAT situation improved and then do additional steps if needed. One is setting up your internet router and the other is potentially setting up your firewall software. There are two things you will have to look at when trying to get better connectivity in For Honor. Strict can only connect to NAT Open players Moderate can connect to other Moderate and Open NAT Open can connect to everyone. This should also provide some help to those of you having the NAT Unknown issue and generally help with disconnection error codes like 1694332663, 1088431700, 33974325484995. There is hope for all of you out there having their network connection recognized as NAT Strict (which means you can connect only to people whose NAT status is Open and if your friends are also NAT strict you can’t play with them), but you will have to do some more complicated tech stuff to get NAT Open or at least get NAT Moderate status. During my experience with the For Honor closed alpha I initially had this problem and joining matches took forever or would completely fail.
Playing For Honor multiplayer is an exhilarating experience, but having NAT Strict network issues, that affect joining matches, can really hamper your enjoyment.
