Cisco 831 router, static IP, DSL, CRWS is hanging

[slikrik98]

Greetings,

I have a DSL account with a dedicated static IP address. My DSL modem is in Bridge Mode (so the line doesn't terminate at the modem). When I manually set my workstation to use the static IP, everything works fine (and this post is proof of that), however I can't seem to get my Cisco 831 router to work. I go to Setup Scenario, and then select the "static IP, no termination" option, enter my gateway, dns servers, wan ip address, and subnet mask (I leave the domain name empty). When I click "Apply" however, the progress bar seems to go on infinitely (I let it run for 30 minutes, and it still said "applying settings"). Any ideas?

Hi,

What browser are you using ? CRSW supports Netscape 4.5 or better (but not Netscape 6.x) and also Internet Explorer 5.0 or better...

I am using IE 6.0

This could be either a browser thing or a router thing ..it's best to eliminate the browser first.

Do you have the latest version of Java on your machine ? It might be worth checking that ...

Paresh.

[slikrik98]

yes, i have the latest java version. perhaps there's a way to get the same configuration through IOS ?

[pkhatri]

Sure...

Instead of using CRWS, you can just try and telnet to the router's IP address. Once you are in, you can use CLI commands to make your config changes...

I'm not entirely sure what commands i need to use to replicate the CRWS setup options, which include:

1. WAN IP address

2. DNS server #1, #2

3. Gateway

4. subnet mask

Here's what I was able to find (they may or may not be the right sequence of commands):

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

enable

configure terminal

interface ethernet 1

ip address ##.##.##.## ##.##.##.## (the first is my ip address, the 2nd is my subnet mask)

ip name-server ##.##.##.## (this is my primary DNS)

ip default-gateway ##.##.##.##

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

after shutting down the IOS, i opened the CRWS again, and the WAN IP was correct (from what I had done through telnet), however, there was no value for DNS servers, and I still had no connection.

I'm concerned about the CRWS not working (still, it just hangs when I try to use the setup utility). Any thoughts, and can you give me specific IOS commands to replicate the CRWS configuration?

Thanks!

Hi,

If you log into the 837 and then issue the following command 'sh running-config', it will output the current config for the router. If you could then post that config, I'd be able to better advise on how to configure it up...

The only thing that I see missing from your config is:

ip route 0.0.0.0 0.0.0.0

Pls enter that in see how you go..

Pls rate posts that help.

I tried that command, but got an error message, "invalid next hop (the router's IP)"

[pkhatri · Accepted solution]

It should be , by which I meant, it should be the same as the IP address configured by the ISP on their router's link towards you. It cannot be your own router IP...

Paresh

[slikrik98]

I understand that, and made the ip 70.21.x.x (my ISP-assigned IP address). My router IP address is 10.10.10.1.

[pkhatri]

Could you tell me what the last octet of that IP is ? And the subnet mask that you are using on the WAN link ?

Thanks,

Paresh

[slikrik98]

I'd prefer not to post my public IP address, but if it's necessary, perhaps I could. The subnet mask is 255.255.255.0 (if it helps, the gateway address, as specified by my ISP, is identical to my IP address except the last quartet is 1)
