Pdaan muna..
Sure kbng tama ung default gateway n tntype mo s browser.? To make sure..
open > Cmd
Type: ipconfig
a list of numbers should come up. After that, open up your web browser. Look for the number that comes after "Default Gateway"
Enter that into your web browser. It will take you to a page that might ask for a password. Try "admin"
From there you go to basic settings and there should be spots for you to add ports acceptations.
Add them then "apply" or "save" the settings.
After that it will ask you to reboot for the changes to be saved. Do that and you should be good to go man. Make sure you allow the ports through your firewall too.
Good Luck.
