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.

The Netopia Main Menu Interface

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:
NQG_039: NAT and the Basic Firewall

sounds like your belkin router is not setup as a DHCP server or the DHCP is disabled. The DHCP in the belkin assigns addresses to the internal network, the error "waiting for network to initialize" means that the phone is waiting for an IP address, to which its not getting. When you connect directly to your modem you get an IP from your Internet service provider. I'll bet your internal network is setup using "static" ip addresses, if thats the case you will need to surf into the phones web console and set a static IP address. Or the opposite, enable DHCP in the belkin. hope that clarifies things a little.

Check on the router if you are distributing enough IP addresses.

Meaning that the IP Address of the print server is different from the computer's IP Address.

If you're computer has a static IP Address, you need to assign a static IP Address for your Print Server. To assign a static IP for the print server, you need to open the PSAdmin utility on your computer, locate the TCP/IP and click the plus (+) sign. Double-click the IP Address and you may change it from there.

Make sure that the IP Address of your computer, router and print server are in the same IP range. And make sure that you could ping the IP of the print server.

Then configure the printer port settings and you should be able to print.

Have a great day!

1.) To set up a static Ip address on your computer, click start, control panel, network and internet connections, network connections, right-click on local area network, click properties. In the window select tcp/ip, then click on the properties button.

Since your default gateway address is 192.168.2.1. Click on the selection titled 'Use the following ip address' Your Ip address should be 192.168.2.2, subnet mask 255.255.255.0, default gateway 192.168.2.1. Then in the next section click on the selection titled 'Use the following DNS server addresses' Preferred DNS would be 192.168.2.100 and alternate would be 192.168.2.200. click ok and you are done.

2.) As for the second problem, refer to the following link from the intellinet website. http://portforward.com/help/pfprogression.htm

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

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.

What is the manufacturer of your router so I can get a user guide and taylor the instructions if needed?

Generally I would statically address the device to be forwarded to. If your router address is 192.168.1.1 and Subnet mask of 255.255.255.0 and it's DHCP server controls address 192.168.1.100 for 50 leases to 192.168.1.149 then consider using the range 192.168.1.2 - 192.168.1.99 uniquely as static IP addresses. There are more starting at 192.169.1.150 but let's ignore them for now. In the network adapter to recieve port forwarded content assign a static IP address based on the above as say 192.168.1.15 with a subnet mask of 255.255.255.0 and a default gateway of 192.168.1.1. The DNS addresses should also be static however depending on your router there may be an option. Some routers allow their address to be entered as the DNS address and pass requests as appropriate to the DNS servers loaded in their lan configurations, otherwise you will enter your ISP supplied DNS addresses into the network configuration.

Now that we have established a stable IP address to forward the port to we need to tell the router everything it sees for port 5060 gets forwarded to IP Address 192.168.1.15 port 8000. If detailed instructions are needed I will need to know the manufacturer and model of your router.

Please provide the additional information and any questions in a response to this problem and I will respond when available.

Port forwarding is a method that allows you to run a server behind the router. Port Forwarding opens a specific port to a computer behind the router, allowing all Incoming Traffic on that port to be sent directly to that server. It should be used to setup servers behind the router, typically Port Triggering (Answer ID 344) is a better choice for non server applications (Such as instant messengers and game servers). Below is an example of how to setup Port Forwarding. For our example we will be setting an FTP Server and a Mail Server that uses SMTP and POP3. FTP uses ports: 20 and 21 SMTP uses port: 25 POP3 uses port: 110 Getting Started 1. You must set a static IP address on the server. If you're unsure of how to do this please go to Answer ID 534 for information on setting a static IP address in Windows. 2. Once the static IP address has been assigned please go to your desktop and double click on Internet Explorer (Located on the Start Menu in Windows XP) 3. Once "Internet Explorer" opens, please type http://192.168.1.1into the "Address Bar" and click GO 4. The "Enter Network Password" window will appear. Skip user name and type admin (admin is the default password) as the password, and click OK 5. This will bring up the routers "Setup" section. Look under "Domain Name" and check what version of the firmware you're using. 6. You will need to click on the Advanced tab to the very right. Once the "Advanced" tab comes up please go to the Forwarding tab. Firmware prior to 1.32 This will not work with firmware prior to 1.32
