The reason I made this tutorial, Because I noticed there's a lack of information about portforwarding.
Things you should know:
Portforwarding - Some people may face "Agent Error" that's because your network is trying to access to game's ports but your network is blocking, So that's the reason why you are getting Agent Error.
Wi-Fi connection and Wired connection:
The Wi-Fi connection is connecting from a distance without a wire.
A wired connection is when your computer is plugged with the modem/router.
Bridged mode and Router mode:
Bridged mode is a type of a mode that it's like.. Whatever hard to explain but you cannot access the default gateway if you are using Wi-Fi.
Router mode is the most common mode they use, You can access the default gateway.
How to connect to default gateway to open ports / change settings.:
To know your default gateway address go to: Start >> Run >> and type "cmd" in the small box without ".
Once the cmd is open type: ipconfig.
You may see lot's of displayed information, But you want the right address for the router. For example mine is "Wireless LAN adapter Wi-Fi"
Below you can see: Default gateway: (Mine is: 192.168.0.1)
So that's some basic information of how to access to the router.
How to port forward:
As I said above, copy the default gateway address and copy it to your browser.
As you may notice, Yours might be different, That's because the modem is different than yours.
What if you don't know your username / password?
Now, if the router has default factory you can already thank god for that.
Go to your search engine, Type the model name of your router and search for (Default gateway login factory)
If your you can't still connect call your ISP to give out your login / password.
Okay now let's port forward GunZ:
Go to portforward.com and choose your brand model and press the search button.
Below, There will be a list of games, There you go, Choose GunZ or whatever.
There will be a step by step tutorial how to portforward.
Let me show you a picture of my portforwarding to GunZ:
There you go, To make sure the ports are open, Download the application at portforward.com it will try to access that specific port.
Note; If you still face any AE's go on and disable DMZ if it's enabled.
Hope this will will help lot's of users!
