877w simple internet access configuration, problem

Hello everyone!

I have recently bought an 877w ADSL router.

Installed and tried to configure it last week without success.

I log in to it. Run the guide, entering all the information. But after that no client have internet access.

And i cant get any real status from it, in the GUI i cannot find any logs, or see if it have recieved any IP from the ISP and so on.

The only status i get is wan: UP.

The clients get their internal IP ok.

Hope someone can help me. Thanks

Daniel

Is there really no one that can point me in the right direction?

Hi,

If you are not familiar with Cisco, configuring a router would not be an easy thing to do.

The best you can do to have it running without any particular problem, is to call your ISP and ask for some help.


Best regards,

Please post your router running config inorder to trace the issue.

Please rate the helpfull posts.

Thanks for your helpful answer! I will certainly post the config as soon as i can. (this evening)

Hi,

If you are using SDM to configure the router you may not have a default route set up.

If you can ping an external address from the router when connected to it via telnet or a serial cable, but can't ping from a connected client, you may be missing a NAT command.

These two faults are quite common when setting up a router for the first time.

Post your running config and im sure someone will be able to help you.

Also get the guidlines from you ISP for connection details such as pppoe/pppoa vc info etc.

Many ISP's actually provide basic configs for low end cisco routers. See if they have some sample configs you can adapt to your needs.

Regards,

John.

Thanks for your reply!

-----------------------------------------------------------------------

Cisco Configuration Professional (Cisco CP) is installed on this device
and it provides the default username "cisco" for  one-time use. If you have
already used the username "cisco" to login to the router and your IOS image
supports the "one-time" user option, then this username has already expired.
You will not be able to login to the router with this username after you exit
this session.

It is strongly suggested that you create a new username with a privilege level
of 15 using the following command.

username privilege 15 secret 0

Replace and with the username and password you
want to use.

Hi Daniel,

I have made a simple 877w config for you.
See the attached config for your reference.

Please rate the all helpfull posts.
Regards,
Naidu.

Wow. man thanks for your help.

Tough, you have used it for ppoe, its not used in this ISP.

(Telia Sweden)

It should use:

RFC 1483 Routing (AAL5SNAP)

or

RFC 1483 Routing (AAL4MUX)

(Dont know wich of them, but it should be one)

Could you make another config for this?

Is there any simple way to upload your config directly to the router?

After some googling it seems that Telia shoudl use

rfc 1483 "Bridged"

That is not even an option in the configuration? :S

It only have to version of "routed"

Hi Daniel,

It is simple you can just refer my attached config and do the necessary changes as suite to your ISP.
And also I would suggest you to get back your ISP wherever required.
For example I reached my ISP on many things while configuring the router as suite their network. Your ISP definetely will help you and it is important to reach them in such a typical network config.
It is not wrong to reach your ISP for any kind of information.

Gud luck.

Please click on the correct answere if this answered your question.
Regards,
Naidu.

Thanks again!

How do i access the config file for editing? Do i download a file, edit it and then upload it, or should it be changed "on the fly"?

Getting a bit worried about the RFC 1483 though, tested them both out, and tried to ping an outside computer from the Telnet, and nada.

Dont know what the ISP could tell me, since there is only two RFC modes, and none of them seem to work?

Hey!

I think i found a problem with at least the internet connection.

In CP express, when changing from SNAP to MUX, it loads the configration, all success.

It deletes the ATM0.1 and starts ATM0.2.

But then when the router is shut down and started up again. (wich is required from the ISP)

Its back to SNAp and ATM0.1?

Hi,

You need to save your config.

CCP/CP express/SDM/SDM express will have an option to write the running config to memory.

Alternativley connect to the router using a telnet program like hyperterm and issue the command WRITE MEMORY.

You can connect to the router using TCPIP or using a serial cable. Most cisco people have a collection of light blue coloured "rollover" cables.

Many new routers have a USB port for configuraton as it is hard to purchase new computers with a serial port on them. The USB port on routers is recogised by Windows as a USB-serial convertor.

You should set up a TFTP server so that you can save versions of your config.

A free one is available from solarwinds that works quite nicely.

Install the TFTP program on your local workstation and make a note of the workstations IP address.

Then you can use the command COPY RUN TFTP to copy the running config to a text file. The router will prompt you for the IP address of the TFTP server and what filename you want to save the file as.

Have you been able to ping internet addresses from the router when the connection details are set to MUX?

hello again!

Thanks for your very informative answer!

I use CP express, and also Telnet.

Is there an FTP server on the router where the config file is, you mean?

And to the for the moment most importat thing, i can not still ping an outside adress from telnet, even when using mux.

That scares me a bit? How does that come?

Please give me some ideas about that!

thanks'
