Port Forwarding trouble!

Hey everyone I'm in the process of making my own Runescape private server and the only thing that I have trouble with is port forwarding! I have Verizon Fios, so when I type in my default gateway it goes to a login page.

Then whenever I type Admin and for pass Admin it says invalid user name or password, so I try leaving the user name blank and it still doesn't work! Does anyone know why it's doing this to me any tips? Does it matter if I'm not on the computer thats hooked up to the router? Please help I've always dreamed of having a private server.

 

Try
User: Admin
Pass: <leave blank>

 

Tried and failed, thanks for trying though.

 

user: Admin
Pass: Password

If this fails contact your router providers and ask them... They will tell you default and if it has been changed however they wont tell you what it has been changed to UNLESS you provide them enough info that you are in controll of the router.
