Can someone help me fix my firewall?

[duritz]

I have charter pipeline going through a DLink DI-614+ wireless router.

I have 2 pc's hard wired to it and 2 wirelessly connected.

I don't have it configured right b/c IRC doesn't work half the time complaining it doesn't have an authentic IP address. My personal website that I have on my harddrive using Windows XP Pro stopped working as well. And I have trouble sending messages through trillian sometimes and cannot view or send webcam information.

Here is the link to the tech support for my router: http://support.dlink.com/Products/view.asp?productid=DI-614+

Here are screenshots of my current settings (all factory)

If someone can please help me I'd be forever grateful

Welcome to the wonderful world of NAT.

Your IRC problem is probably because an ident server check is failing.
Your webserver will need port 80 forwarded to it.

how do i forward port 80 to it?

and how do i fix the webcam issue? everytime i try to view a webcam or send a file it either says connection failed or the webcam screen is just black.

There are two things you can do, the easiest first, your router IIRC (i have the same one but haven't set it up yet, still using an old linksys) has the ability to setup a DMZ DeMilitarized zone, what this essential means is that for one ip address on your network the internet will appear transparent, as opposed to the NAT that it is going through now. This is not that safe but only requires going into the special section of the router and entering the ip of the machine you want in the zone. This is obviously not compatible with DHCP and more than one machine because you will not be certain which machine has the DMZ address after a reboot.

The second safer but more difficult way, is to set up a passthrough on each port of the service that you are having problems with. this essentially tells the router that incoming webtraffic for instance (port 80) should be sent directly to an ip adress such as 10.0.0.2. The downside is that you need to creat a port forward for every service including IRC and any P2P network you are having issues with.

there is no way to just disable the firewall completely???

 

[skyking]

it is not a firewall feature that has you stumped. It is PAT/NAT, the protocol that lets you have multiple computers with one IP.

 

[duritz]

well can anyone give me an exact step by step procedure on how to do what Bart or Kaiynne told me to do?

i'm a networking idiot when it comes to these things
