Hey everyone,

I am every new to this router configure, and my boss just asked me to configure this CISCO 877W for the office network. I have tried my best to get codes from everywhere and put them together. However, it doesnt work, please could anyone point out the mistakes please. Thank you so much for your help.

I put the router on the DSL line, the PCs can get IPs from the router, and also I could log into the router. But there is no interenet connection, also I cant ping anything from the router.

We are using BT ADSL2+ connection, PPPoA.

Are you using SDM to configure or just cli? Can you telnet to the router and enter

sh dsl int amt0 and post the firmware version

 

As you say you copied your config from elsewhere, are you sure you used your own details in the areas you needed to, such as the PVC 0/38 part.

 

I don't know squat about Cisco routers, but the date is a smile away..

 

Hey guys,

Thank you so much for your replies. I have double checked with BT, and they are saying we are using:

ATM Circuit Identifier: VPI:0 VCI:38
Connection Type: PPPoA

 

Are you using the SDM(Security Devices Manager)?

 

access-list 1 permit ip 192.168.1.0 0.0.0.255 any

^ thats what i use for my NAT source list.

 

What about

Code:

show pppatm session

 

ThomasMc, Thank you so much for your replies & help, and I am sorry the late reply for the post.

anyway, I have had a look at the Security Device Manager from CISCO. It would be a very handy tool to have for stupid people like me. I will contract CISCO to see if I could get it somehow.

anyway, back to the problem, I have checked the pppatm session, but at the time, the boardband phone line was not connected. Not sure if this will affect the trouble shooting.

Thank you so much for your help.

 

yes it affects the command output.

Have you tried changing your NAT statement to the one i posted?

 

danielno8, thank you for your reply. Do you mean:

HTML:

ip nat inside source list 1 interface Dialer0 overload

change to ==>

ip nat inside source list 1 ip 192.168.1.0 0.0.0.255 overload

?

Thank you.

 

No this line:

access-list 1 permit 192.168.1.0 0.0.0.255

change to:

access-list 1 permit ip 192.168.1.0 0.0.0.255 any

 

You should get SDM with this router, did you get any CDs in the box? Also any update on what Danny is suggesting?

 

danielno8,

Are you sure that change is going to help?

 

nope, but it definately won't do any harm!

 

danielno8,

What kind of access list is "access-list 1?"

 

aren't you the one with the CCNA?

 

Globis, i just re-checked my config and i have the same line as you, so no need to change out that line i suggested!

 

Ok so if its ok with r.h.lee then could you connect the line to the cisco877 and then re-run the show pppatm session

 

Hey everyone,

thank you so much for all the help and advise, the router now is able to get the broadband connection, and it works fine for all wired connections. However the wireless doesnt work, it looks like the PCs couldnt get an IP from the router, but the wired ones can. Is there any suggestion why the router is doing this?

Thank you so much for all your help guys.

the current running code on the router:
