External internet address conversion- NAT

I am trying to have the true IP address that is coming "into" the router exit the router. Is there a way to "turn off" the NAT with this modem.

I just want the true address to pass thru the modem as I am trying to set up a network that runs thru a router and contains an IP phone that also has NAT functionality.

Any responses would be greatly appreciated on this end.

Hi, Our modem seems to work fine when plugged directly into a computer (we get internet okay), but if we plug it into anything else it won't get internet. We've tried two different routers and a Wii and...

Without further information, my best guess is that your modem has the same IP address as the common IP address for routers and probably the Wii. Most wireless routers have the address
Try connecting a computer using a hard line (a network cable) to your router and type in this address, it will most likely come up. If it does change it's static address to (actually any number behind the last period above 1 and under 255.). Also set its gateway to to access your modem. (Also in the router settings which are found by typing the address mentioned above, Be sure to note this new address if you want to access your router without resetting it and using a hard line again. The Wii should automatically pick up signal from the wireless router. If for some reason you want to switch between the Wii and a Router by way of hardline, you must contact the maker of your cable modem (or cable company) and find out what the IP address is in order to access it's settings (the same way; by typing it's IP address into a browsers address bar.) By setting the modem to have a different IP there would be no conflict with the other products which (rightly) have the IP address of as a default.
Hope this helps!

Will not generate IP address. Internet light does not come on. New modem.

1. power cycle the router
1.Log into router. Using either to in a browser window that is ( internet Explorer or Firefox)
2. Verify wireless router name( on the computer) >>> ( on/off) ( router status window)
3.Note router name you are connecting to.
4.. Check the laptop do ipconfig /all to see current IP addresses.
5. Set the laptop up in the router by WEP KEY or MAC address. This set up in the "security tab" in the router. using or to access through a browser.
6.Note router name you are connecting to.
7. Move the laptop about 20ft away and try to log on to the internet.
This is for all routers to set up wirelessly.
8. check for firmware update at the manufacturers site for your model router

My NAT setting is strict. ive tried everything i know to change it but cant. i have a silver motorola modem wit a black and blue linksys router but i cant figure out how to change the Nat setting. Im...

Microsoft has a support page to help you with your NAT settings. The prescribed solution is to "open" the following ports on your router:
  • UDP 88
  • UDP 3074
  • TCP 3074

1- Using your Browser, Log on to your router (by normally typing in the192.168.1.1 address check your router's manual to see what the defaultgateway address)

2- If you already know how to log in to your router, then skip thisstep. If you have never logged on to your router then more than likelyyou still have the default initial log in credentials (username: admin- Password:1234 ..... Again check your router's manual to be sure). Theminute you log in you need to change that password immediately, mostnetwork-savvy folks know that 90% of the people out there never resettheir router's initial password and they can log on and make anychanges to suit their needs, including locking you out of your ownrouter.

3- Once you are logged in click on sercruity, scroll tot he bottom and make sure "Filter Internet NAT Redirection" is set to "disabled" ,

4. now click on advanced routing
make sure
Nat is enabled.

5. now click on applications and gaming.

you should be able to find two advance settings (One if for NAT - and the other is for Upnp)

4- Let's start with the NAT setting changes, and we will edit theUpnp settings at the end.

6- You will need to find out what the static/dynamic (preferablyStatic) IP address you xbox360 has. To do so, go to the Dashboard, goto the Console settings page, and click on the network settings to seethe IP address (should be something like 192.168.1.x). You will needthat IP address to enter into your NAT table on your router.

7- Once you got your XBOX's IP address enter it in the NAT PortForwarding table (From - To - IP address:)

8 - In the first line enter 88 under both "From" and To" fields, thenenter the IP address of the xbox in the field where you are to enter anIP address. (this is for UDP port)

9 - Repeat the same step for port TCP (which is 3074)

10- If these changes do not help open your NAT settings, then try theUpnp option. Click on your Upnp Advances settings enter the same information with the ip, and make sure UDP are enabled and checked for. use the port #s for your info as well in the chart. you can name them what ever u want under the application column.
  • UDP 88
  • UDP 3074
thend o the same for

TCP 3074
just make sure the tcp is checked and not udp.

if that doesnt work we can do a full reset on your router.

Reset for most routers with a reset button on the rear panel
Write down configuration information such as IP addresses, securitykeys, opened ports and services, etc., that you modified. (The defaultusername is admin and the password is either password or 1234. Try these before resetting the router.)
  1. Press the reset button on the back until the test light blinks.This takes about 10 seconds. (To avoid accidental resets, the smallbutton is recessed. Use a pen or paperclip to access it.)
  2. Release the button.
  3. Wait for the router to reboot.
  4. Log in with the default password.If the router configuration was not cleared, try these additional steps AFTER the router has finished rebooting.
  5. Unplug the router's power.
  6. Press and hold the reset button. While the button is held down, reconnect router's power.
  7. Continue to hold the reset button for 20 seconds after reconnecting the power.
  8. Wait for the router to reboot.
  9. Log in with the default password.
please rate me, and mark this fixya if it has helped.

Webcam Access through SB4220 Cable Modem?

it sounds like you have configured the router correctly. what you might be doing wrong is trying to access the camera from your internal network using your external ip address. this will not work... you need to get someone on the "outside" to try the ip address.

Recently I subscribed ATT DSL Service conflict IP Address

the motorola modem that att is using uses 192.168.1.x subnet. log onto your router and change it to 192.168.b.x where b is any number between 2 and 254 (just not 1). You should also log onto the modem and change the setting that allows it to share the external ip address with the router. You will need to do this if you plan on accessing your network from the internet.

Can't open port to uTorrent

virtual server also known as port forward, try to look for this phrase, if not u may also find some word with NAT or Nat table.
Anyway routers must have this function in general.

By the way, how did you make your ip static, manual from your mac or the routers'?

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 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 network with 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 21 21 extendable
ip nat source static tcp 21 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 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 21 interface Dialer1 21 extendable
ip nat source static tcp 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.
