I have a cable modem with two static ip given by my isp. I use a switch at the front end in order to split the static ips and behind the switch I have two independent routers each connects with two PC. One static ip works with one router but another static ip did not work with the other router. Does my configuration work? and how to solve the problem?

    I restore the registry of both PCs and paid the technical support of Linksys to get into the Linksys router. Then they all work. I used $50 USD for this senario but I think its worth it. I learnt a lot from the technical support of ShawCable, fixya(wiz) and the Linksys support. I have no complaints. I am a MCSE and MCDBA ( had to pass 7 exams before I got the qualifications). I am also an A+ professional. I have 3 degrees: B.Sc.(physics) M.Sc.(physics) and M.A.Sc.(electrical engineering). However I was unemployed since 1992 and doing some odd jobs then. Luckily my wife has a job to support the family. I am unemployed for 17 years! Every time I was fouled out near to the final stage of selection. How unlucky I am! Hope to get a decent job before I die. Good luck to everybody who is unemployed!

Do you have separate usernames and passwords for both IPs?

How to configure a router


  1. Login to the router page but typing http://192.168.2.1 on IE
  2. Check if you have a WAN IP or Internet IP
  3. If it is 0.0.0.0 then there is a problem
  4. If your internet provided is Cable you may have to do MAC clone
  5. If your internet provided is DSL you have to configure the router in PPPoE mode
  6. You will get WAN IP and will be able to go online
  7. Change the SSID which is nothing but the wireless network name
  8. Change the security to WPA or WPA2 and setup a security key

Couldn't get internet via Wirless Router


HI! I bliv u are having some issue setting up ur router.. I will be more than glad to assist u. here are the steps u need to do:

1. press the reset button on the back of the router for 20sec..while pressing the reset button, unplug the power plug and after 2secs while pressing the reset button plug it back in and press for 30secs after that unplug the router for 15secs then plug it back in..once all the lights are solid and ok
2. connect the ethernet cable to port1 of the router and the other end to the lan port of your computer..
3. pull up ur browser then type at the url:192.168.1.1.or 192.168.0.1 or u can check the routers default gateway by right clicking the network icon on the lower right of your task bar and click on status and it will show the ip address of the computer, subnetmask and default gateway, the default gateway is the routers ip address, once u type in to the url, it will ask u the username and password, by default the username is admin and the password is 1234 or just leave it blank
4. it will show the setup page of the router. u can set the router on the specific internet setup that u have.
a. if ur isp is a cable company, normaly u need to do a mac clone on the router setup page by cloning the computer that is reg to the cable company, how to determine it. ex. the computer that is reg to the cable company is a desktop or laptop, if this computer is connected to the modem directly and u can access internet.
b. once u determined it u need to connect this computer directly to the router and do a mac clone and set ur internet settings to auto-dhcp..then save the settings and after that, unplug to the power of the modem and router, plug in 1st the power of the modem then once all lights lit, plug in the router, then once all lights lit, try to pull up a browser that ur computer is connected directly to the router.. ur cable connection shud be, cable from the modem will go to the WAN port of the router and connect ethernet cable on port1 going to the lan port of the computer..once u can access the internet, u can now access again the setup page of the router by typing at the url:192.168.1.1 and u can setup the wireless settings, u need to create a ssid or wireless name and a security..
5. If ur isp is a dsl normaly they give u a username and password to connect to the internet, ur settings on the router should be PPPoe
6. If ur isp gives u a static ip address settings, u need to set the router to isp setup.
a. how to check the isp of the isp given to u..
1. click on start
2. run
3. type cmd
4. it will show a dos prompt
5. from the dos prompt type ipconfig/all
6. it will list the ip address, subnet, default gateway, dns server
this settings should be type in to the settings on the router for static ip addressing..

With the steps that I given to you, it was mention earlier that u used the pppoe, dhcp, but not static ip, if your computer is directly connected to the adsl modem it works perfectly. this is the specs of ur modem:
Supporting 1483B bridging and routing function Supporting DHCP server, NAT/NAPT , PAP/CHAP, IP Filter, Firewall, protocol block Built-in PPPOE/PPPOA dialing..

you can try two option:

1. your modem is equip of supporting dhcp server, if u can access ur modem and set it to bridge mode so that the dhcp server wont conflict with the router bcoz the router has a dhcp capabilities as well.
2. you need to disable the dhcp of the router so that the modem will act as the server and will give ip address to your computers..

this 3rd option will be your last solution if both dont work..

try to check the ip address of the modem, if the the ip address of the modem is 192.168.1.1 and the ip address of the router is 192.168.1.1 as well, connect your computer directly to the router and change the 3rd octet of the ip address, ex-192.168.1.1 to 192.168.2.1 then your connecttion should be , the cable form the adsl model goes to the port 4 of the router and the router should be set on a dhcp settings..

I hope this solution will help you. good luck

if you have any querry pls feel free to get in touch.. 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.

RCA DCM425 modem ethernet connection won't work


The setting for the Computer 1, use the network connection wizard to automatically configure the modem to work as a server station. Next, set the IP number manually and the DNS at automatic or is given by your ISP. Now the Computer 2 (workstation) should be connected to a Hub/Switch. The same, go to network connection wizard and select the appropriate connection setting, there are view samples for the connection types so explore them. After the setup, try loading your internet browser.... When done, it should work fine. Keep me posted for any problems.

Static ip address


It is a ADSL Modem. It should have all ports open. In order to set a EXTERNAL static Ip address, you would have to call up your ISP and ask for a static IP address.
