Please tell us ALL the equipment connected to your network. The duplicate IP address seems to indicate you've assigned your static IP address in the range of the DHCP server in the router and another assignment is stepping on it.

Assign the static IP address OUTSIDE the DHCP server range, but in the same subnet.

umm...well i only have 1 PC connected to the router
sorry...im not exactly 'smart' when it comes to IPs and all this, so im kinda lost,what is the DHCP range?
on the Wan settings in the router i put
ip address : 192.168.1.2
subnet mask: 255.255.255.0
gateway: 192.168.1.1

On the Settings in my pc (Internet Protocol) i put
Ip address: 192.168.1.2
Subnet mask: 255.255.255.0
Default Gateway: 192.168.1.1

Preferred Dns: 192.168.1.1
Secondary Dns: Blank

Am i doing something wrong?

That all looks fine, I can't imagine where the duplicate IP address is coming from.

How about posting this?


Hold the Windows key and press R, then type CMD to open a command prompt:

In the command prompt window that opens, type type the following command:

Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

IPCONFIG /ALL

Right click in the command window and choose Select All, then hit Enter to copy the contents to the clipboard.
Paste the results in a message here.

If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

This is wrong :
"on the Wan settings in the router i put
ip address : 192.168.1.2
subnet mask: 255.255.255.0
gateway: 192.168.1.1"
It seems to me you should have your ISP details in this section. Can't be more specific as you haven't said what router you have.

Sounds like you are configuring the WAN port for a Static IP instead of configuring Port Forwarding. This error
ERROR- DUPLICATE TO LAN IP NETWORK
says you've set the WAN IP the same as the LAN IP.
Here's the page for your router at PortForward, this should walk you through the setup. Just pick the program you are trying to forward the port for.

You don't need a static IP for the Router, you need a static IP for the PC.
Though it will work most of the time using DHCP. Your IP address won't change while the system is powered, and you should get the same IP address as long as the PC is not turned off for longer than the DHCP lease period. Even then with only 1 PC you'd likely get the same IP Address.

Best to set it up static though. You need to pick an IP address that is outside the Routers DHCP Range.
Easiest way is to log in to the Routers Web Interface.
Click on Basic | DHCP
Set the Client IP Pool Starting Address to 192.168.1.5

Now set your PC to use these settings:
Code:
IP Address. . . . . . . . . . . . : 192.168.1.2
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.1.1
DNS Servers . . . . . . . . . . . : 192.168.1.1
You can follow this guide to setup the Static IP, just choose your OS

Then use 192.168.1.2 as the Local IP Address on the NAT - Virtual Server page.
