Hi everybody,
I need some serious advice regarding what I should do.
My plan is to use my computer to host a small business website. I have cable modem and linksys d-link router. I found a way to set it up (with help of a few website tutorials) for routing traffic to my website, but my isp provider is blocking port 80 (videotron canada) so noone outside local network was able to see my website.
Few days ago I called my ISP and signed up for "business" plan and now I have one static ip and all ports unblocked, but I also got the Cisco 851 (not wireless) router.
The installation guy came and plugged cables from my linksys router into the cisco router, gave me the SDM Cd, said everything was ok(since the litle green light is on) and left after telling me to install from the cd. There was no internet connectivity at this point with cisco router.
The Cd instllation did no go as planned since on the step 2 (after plugging everything as instructed and selecting model number) and clicking on'Launch Cisco SDM Express' button I get a 404 page for the .
LAN Connection is showing 'limited or no connectivity' and I am unable to connect to router or internet from my computer (I do not and have serial cable, just ethernet cables).
The cable modem and linksys router are still fully functional and I am currently using those.
I have windows xp professional
2100mhz dual amd processor
1 gig of ram
200 gig free space on hd

I managed to install cisco SDM express on my pc and jdk but that is as far I got.
Should I just put the cisco 851 on the shelf and see if the linksys setup works now (with ports unblocked) or does cisco 851 do things I desperately need to run my website?
Thanks for getting this far in reading this post, any comments and tips are greatly appreciated.
I know I am in it over my head, but that is why I am here for you to enlighten me!
 
he doesn't have the username and password.. thats as far as most telcos around these parts go for locking them down..
it will likely remotely log his failed password attempts.. (where i work would) not sure about that provider though..

its touchy though if the router config is modified they could cancel the service. you cant really turn off the console port though.. or else how would the telco get into the router if something happened to it?
 
Right, but I mean maybe they should keep the router in a lock box, or on their premesis.

Thanks everybody for all the info and help troubleshooting this problem!
I managed to set it up :)
For orher suffering souls that might run into the exact same problem here is a short walktrough for setting up:
equipment used : cisco 851 router, Linksys d-link router, cable modem, pc winXP.

Procedure: On your pc open ip/tcp properties in your "local area connection", select static io and enter:

-ip address: 192.169.1.4 (last number 4 can be any number between 2-49 and this address becomes your computer's ip on the network, for other computer(s) on the network pick different number between 2-49)
-subnet mask: 255.255.255.0
-default gateway:192.169.1.1 (this is the default address for your linksys router

Preferred dns server and alternate dns server addresses can be obtained by calling your cable internet provider (videotron in my case) and asking them.
when you enter these details click OK.

YourISP may have forgotten to send you an e-mail with your static IP, Gateway, Subnet mask and dns addresses. If you do not have those yet, now is te time to call.

Next, plugin cable modem to cable outlet and power, plugin cisco modem into cable modem via ethernet cable (use wan port on cisco router)and plug in power, then connect your linksys router into the cisco via ethenet cable from port 0 (read zero) on the cisco router to wan (internet) port on the linksys router, and lastly connect your pc to the linkys router (any available port) and power it all up.

On your computer , open internet explorer and type: into the address bar, hit enter and the login for the linsys router appears. To log in leave username field blank and enter the word admin into the password field, hit enter.
In the first window that appears (basic setup) chage the first setting ("internet connection type" under "internet setup") to static ip, then in the boxes below enter the corresponding numbers provided to you by your ISP.

Network setup should be left alone (i guess for now)
and router ip aka Local ip Address should be 192.169.1.1 with subnet mask 255.255.255.0
CLICK on the "save settins" button on the bottom of the page.
At this point with all the equipment working properly you should have internet access!!!

To open port 80 for your own server (if that is why you are paying $100/month to your isp now) you have to go to by clicking on "application and gaming" in your linksys setup interface, then type in the following in the first horizontal line: server, 80, 80, 4, and enable check button.

So simple, you are done.

No other modifications are needed except maybe enabling your server to be accessed from the internet in firewall settings. By using online dns services or runinng your own dns server and setting up virtual hosts in your http.conf apache file you can finally host all your domains on your pc. :)

Thanks again to all that helped!
 
On the computer and LinkSys, you probably don't want 192.169.x.x, but rather 192.168.x.x...
