modem settings help? PLease?

What I think you need to do is look at your FIREWALL. I am talking about the firewall on your computer that came with your security software, like antivirus. Most (but not all!) firewalls will allow you to open specific ports by naming them...you should look at your specific settings or options on your firewall for PORTS. Port 80 is a port which needs to be CAREFULLY watched, because it is a typical port which is attacked by hackers. My suggestion is not to make visible or open port 80, ok?

The other thing is, if you have a router firewall, it should have come with a software CD that lets you set up a firewall inside the router. A firewall router can also block port access, so that even if your security firewall opens a port, your router firewall can block it. You will need to find the CD that came with your router and insert the CD, run it as "admin" or "Admin" - those are the standard passwords set by factory default, and then set your firewall up in your router to open the ports.

PORT 80 is a very common port and will be attacked by hackers if you open it or make it visible to the internet.

I recommend you not open that port!

Hackers also have bots that will scan your address and look for any of the other ports as well, so make sure your firewall is set up to be invisible to the internet.
