Sorry for the mic, I've tried adjusting my microphone settings in sound properties but It doesn't let me.
Steps to fix the firewall problem in GameRanger:
Step 1 - Open the port for GameRanger
Step 2 - Make Static IP
Step 3 - Enable DMZ + Add the IPv4 Adress to there.
Note: If you have another router and you want to open a port so It's not a big deal. Just try to find the place you add the ports.
It might be in Advanced Setup --) Port Forwarding or something like that, Just find it, It's easy.
Also with DMZ.
It might be in Advanced Setup --) Port Forwarding --) DMZ
Or Advanced Setup --) FireWall --) DMZ
Default Passwords for the Routers - www.phenoelit-us.org/dpl/dpl.html
Note: If the password isn't --) Username: Admin Password: Admin so try this, Username: admin Password: admin
Just delete the capital word, instead of Admin type admin, it might work.
