I can't find the settings to enable a public IP for my dns server. Where are they or is there another way?


Telephone your ISP -- they can provide this information.

However, most ISPs use 'DHCP' ("Dynamic Host Configuration Protocol") which automatically provides IP-addresses of DNS-servers to any device (your computer, or your router) connected to the cable-modem.

HAve you entered the wep or security code for your router into the x box live.

Wep is the wireless security code found on your routers homepage.

Keep getting cannot connect to primary dns server


you need to call the cable company tell them your ip lease is cycling every 15 minutes, it is a node conflict, they can fix it on their end. if the cable modem is a hacked one, then you just need to clone a new MAC yours is not valid anymore. if not a hacked one, call tech support. good luck!

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.

Port forwarding


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.
