How can i map my public ip address to th natted ip private?

How do I open ports in the Virtual Server? You need to forward the ports used by the application to the server running the application in the Virtual Server, which is present in the router's management screen, as follows.

1. Open your web browser, type in the router's IP address (standard: 'http://192.168.2.1') and press enter.
2. Click on Login, Advanced Setup, NAT, Virtual Server.
3. Enter the port details and enable it as follows:

Private IP Private Port Type Public Port 192.168.2.x xxx TCP xxx 192.168.2.x xxx UDP xxx To access the application, you can open up the ports specific to the application in the special application, which is present in the router management screen as follows:

1. Open your web browser, type in the router's IP address (standard: 'http://192.168.2.1') and press enter.
2. Click on Login, Advanced Setup, NAT, Special Application.
3. Enter the port details and enable it as follows:

Trigger Port Trigger Type Public Port Public Type Enabled 3724 TCP 3724 TCP Y 6112 TCP 6112 TCP Y 6881 TCP 6881-6999 TCP Y
* The port numbers given are just an example. You need to open the ports depending on the application you are using and should get the information from the application provider.

Server List (Port Forwarding) NQG_025 With NAT enabled, the IP addresses of nodes on your LAN are private since they are hidden from the Internet. IP Servers let you pass specific types of network traffic through the Netopia router's NAT interfaces. Once configured, selected types of network traffic, such as FTP requests or HTTP (Web) connections, will be forwarded to a specific host or server behind the Netopia router. Please Note: From the LAN (Local Area Network), you will also be able to access the servers that are responding to requests from the internet, but only using the internal private IP address. Access via the public IP address is not supported from a local ethernet connection. If your ISP is routing you multiple public IP addresses, you can also configure the router to forward all ports in one public IP to a designated private IP address on your LAN via Easy PAT List entries. For those instructions, see Quick Guide NQG_024: IP Mapping (Address Forwarding).
Please Note: If your router is currently running Netopia Residential Firmware with a web "GUI" configuration menu, this technote is not applicable to you. Most 3300 Series Netopia Gateways can be upgraded to Enterprise level firmware. Click Here! to purchase the upgrade key.

Before You Start
Telnet into the Netopia router's Main Menu at 192.168.1.1 (if using the default IP setting). If your network has a different IP addressing scheme, modify this accordingly. Click Here! for instructions on using telnet and Hyperterminal (serial connection).
Login with the user name and password. The Superuser login is required to save changes. If you are unsure of this, contact your network administrator.
Don't forget to press the Enter key to save any entries. Hitting the back space, delete or tab without first hitting enter will undo any changes.
The Esc key will take you back towards the main menu screen.
Once you have completed your configuration, you should reboot the Netopia to save and apply your changes.

Server List Configuration

1. From the Main Menu of router console screens, go to Quick Menus, and select Network Address Translation.
2. Select Show/Change Server List.
3. Select Easy-Servers.
4. From the Show/Change NAT Server List screen, select Add Server.
5. Select Service and the service and port you want to allow. If your service and port are not available in the pull-down menu, select Other. Selecting Other will allow you to enter a specific service port or a range of ports since fields are provided for both a First Port Number and a Last Port Number. To allow a specific service port, the First Port Number and Last Port Number should be the same. Select Okay.
6. Next, enter the Server Private IP Address, or the private IP address of the host/server you are forwarding the service to, and the Public IP Address you want to associate with the same host/server. This value can be left set to 0.0.0.0 if you are using the WAN IP as the Public IP address. Note: If your ISP is routing you multiple static IP addresses, other then the one used for Internet access, you may create more than one server for specific service as long as all servers have a different Public IP Address specified. For example, with two web servers on your LAN you would need to create two Server List entries for TCP 80 (www-http). Since each specific port (service) can only be mapped once using any given Public IP Address, a distinct public address must be used for each TCP 80 server list entry. It is not necessary for you to specify more than one Local WAN IP Address or Public IP Address in your router's configuration. As long as you are connecting to your ISP via a public IP address used for NAT, they are responsible for routing all other IP addresses via that connection.
   

Conclusion
You have now configured your router for TCP/UDP port forwarding. If you have a switched connection (ISDN or Analog), you will need to either disconnect and reconnect your Internet connection, or restart your router for the Nat Server List changes to take effect. If you wish to filter traffic for your static IP mappings, please see the following Netopia Technote:

OK I think the easiest way to connect the xbox to the linksys, is if you configure your XBOX to have a static IP address, because the xbox will not have to pick an IP address every time you connect to the internet using the Linksys router and will not have conflicts with other PCs on your house, if you have any. What the linksys does is to convert your Public IP addres into a Private IP address, so example if your ISP gave you an IP address of: 209.235.205.30 that is your IP address for you, then the Linksys converts that number (NAT) into a private IP address so it can be share with many computer inside your house using a single Public IP address. The Linksys always transform it into 192.168.1.?=any number between 1-256 thats the defaults IP address from the manufacturer but you can change it if you want. Ok enough info about NAT or IP jeje.

Where going to use the default IP addres for an easier setup.

First: On your XBOX 360 dashboard go to SYSTEM, then Network Settings, then Edit Settings, then choose the option manual, here put the IP address= 192.168.1.33 (if 33 doesn't work use another numer like 20 or 45 just pick a number between 2 and 250) ; Subnet Mask = 255.255.255.0 ; Gateway = 192.168.1.1; DNS options put Automatic. And see if it connects. If it doesn't work just post it here, any problem that you have.

So you want the public IP address that your Netopia router is getting to do a 1 to 1 NAT to the private IP address 192.168.1.136? Basically you want to bypass any of the firewall restrictions of the router?

The caveat with this configuration is that if you don't have any other public IP addresses for the actual Netopia router to use then all other devices on your network will now longer be able to access the internet through the router. Only if you have a public IP address that you can assign the router will it be able provide NAT and internet access to the rest of your network.

The 192.168.1.0 network is not routable on the public network. You need your entire network to NAT through your router using a public IP address.

You configuration will work if the Netopia router will allow a 1 to 1 NAT to another node on the network and allow NAT'ing for the rest of your private network concurrently. Of course you need at least (2) public IP addresses in the same subnet as well.

Hope this helps. Let me know if you need better clarification.

Heres a link to a guide which should guide you step by step to obtaining an "OPEN NAT" status

yeh guide.

otherwise purchase "Compatible Xbox 360 Live " Hardware which will give you a Open NAT

To be honest i think this NAT status is a marketing idea on MS part as NAT is Network address Translation , which is the ability to supply computers on the network a Private IP address using the same Public IP Address , and this sounds like port forwarding, but nonetheless goodluck :)

Just a bit of explanation. E0 interface is for inside network (LAN interface). E1 is for outside (ISP or WAN physical interface). Dialer1 is for PPPoE (the "actual"/logical WAN interface). The 1.0.0.13 is ISP provided static IP address for the use of the server. This configuration example is for running FTP server, which uses the standard TCP port 20 and 21.

The LAN uses 10.10.10.0 network with 255.255.255.0 subnet for both servers and workstations. All servers within the LAN use static IP address. The router is configured as DHCP server to give out IP info (IP addresses, subnet mask, DNS) to workstations that are configured as DHCP client.

Basically I suggest that you deploy NAT (Network Address Translation) and PAT (Port Address Translation) to setup your own servers behind Cisco router. The NAT is used to translate the ISP's given static IP address to your local IP address. The PAT is used to translate TCP ports (the port 20 and 21) between the two IP addresses.

When using NAT/PAT, keep in mind that the Internet-accessible servers are seen from the Internet as their NAT/PAT-ed IP address (the Public IP address) and not the local IP address (not the Private IP address). This understanding is very important when you or someone need to test connectivity to the server and/or when you need to create filter (access list or ACL for short) to allow only certain incoming traffic from the Internet and block others.

Side Note:
For more info on NAT/PAT concept, check out the following FAQ
»Cisco Forum FAQ »NAT and PAT; Introduction and Implementations

Instruments used in this illustration are pretty much standard for running your own servers. Please note that IP addresses, username, and password are changed. However, you could always modify the configuration to suit your situation.

This sample configuration assumes that you have a block of IP from ISP. There is a dedicated Public IP address for the router WAN interface (the Dialer1 interface) and another dedicated Public IP address for the server PAT IP address. If you only have a single Public IP address for both router WAN interface and server PAT IP address, there are several ways to configure the router.

One way is to use the same command as shown in sample configuration.

view plaincopy to clipboardprint?

1. ip nat source static tcp 10.10.10.2 21 1.1.1.14 21 extendable

ip nat source static tcp 10.10.10.2 21 1.1.1.14 21 extendable
This one configuration way is suitable when you have static IP address from your ISP and you know exactly what the IP address is. In this case you have the 1.1.1.14 single static IP address for both the WAN interface and Public server IP address.

When you are unsure which IP address you receive from the ISP, or when your Public IP address keep changing; then another way to configure the static PAT is following

view plaincopy to clipboardprint?

1. ip nat source static tcp 10.10.10.2 21 interface Dialer1 21 extendable

ip nat source static tcp 10.10.10.2 21 interface Dialer1 21 extendable
With situation of dynamic IP address, at some point you still need to know the exact Public IP address you receive from your ISP for server connection testing and production time. To find out, you can issue show ip interface brief command on the router. You will then see the associated WAN interface Public IP address.

there is something known as NAT strict that can happen due to many reasons , NAT or network address translator helps in converting the WAN ip address to LAN side IP address or public to private ipaddress . In a case of NAT strict or no NAT type ur PS3 or the router to which you have connected the PS3 is not able to convert the IP address...
Solution: try logging on to the router manager or PS3 settings and enable the NAT ( it would be in a disabled state or DMZ ( de militarized zone ) state )....
If the nat is already enabled Then try to manually configure NAT by opening the port numbers on the router manager or PS3. Port numbers can of UP or TCP protocol depending upon the games ur tyring to play....
If u donno how u do it then contact sony or the people who gave u the router or ur ISP

The ports should be opened only in the router not in the x.box, go to a working pc..


To allow traffic from the internet to enter your local network, you will need to open up ports or the router will block the request.

Because our routers use NAT (Network Address Translation), you can only open a specific port or ports to one computer at a time. For example: If you have 2 web servers on your network, you cannot open port 80 to both computers. You will need to configure 1 of the web servers to use port 81. Now you can open port 80 to the first computer and then open port 81 to the other computer.

Step 1 Open your web browser and enter the IP address of your D-Link router (192.168.0.1). Enter username (admin) and your password (blank by default).

Step 2 Click on the Advanced tab at the top and then click Virtual Server on the left side.



Step 3 Check Enabled to activate entry.

Step 4 Enter a name for your virtual server entry.

Step 5 Next to Private IP, enter the IP address of the computer on your local network that you want to allow the incoming service to.

to check ip in your pc.. go to start menu click run.. type cmd and hit ok

in the black window enter ipconfig and hit enter, you will find the ip address

Step 6 Choose Protocol Type - either TCP, UDP, or both. If you are not sure, select both.

Step 7 Enter the port information next to Private Port and Public Port. The private and public ports are usually the same. The public port is the port seen from the WAN side, and the private port is the port being used by the application on the computer within your local network.

Step 8 Enter the Schedule information.

Step 9 Click Apply and then click Continue.

This would fix your problem..
