Hi all,

This isthe first Cisco router I have tried to install. I cannot get internet access setup, can any of you see any glaring errors? I think it must be to do with the NAT setup. When I run the test on the adsl connection it comes up as fine. Help very much appreciated!

Rob

sorry, type in title - it is an 877 router!
 
Your NAT config looks fine and I don't see any glaring errors either. Try issuing the 'show ip int brief' command and see if you are getting an IP address allocated to the Dialer0 interface.

If not, issue the command 'debug ppp auth' and, if you are connecting via telnet, issue the command "term mon" to see the output. You may just be failing to authenticate with your ISP - that's my guess anyway.
 
Debug ppp authe or autho
Kisco, don't forget that there's ppp authorization and ppp authentication.

You can sh int, and if the dialers are bound to virtual access with the line protocol in the up state, you should be good.
Go to this link
and put that encrypted password in there
ppp chap password 7 022B0549050F0A791B---that one---everything past the 7. In other words, do not post these! They are easily cracked!
Add these commands to the di0 interface...
ppp authe pap chap callin
ppp pap sent-username xxxxxxxxxx password xxxxxxxxx
ppp ipcp dns request
ppp ipcp wins request

I had the same problem you did, and I put those commands in, and BAM! It worked...

I have done 'show ip int brief' and I am getting a correct ip on the Dialer0 interface.

I also put the commands in as you suggested, castlemadeofsand, but it did not seem to make a difference.

With the "sh int" command what am I looking for? As you can tell, novice would be an understatement to my router knowledge!

Any more ideas?

Thanks in advance!

Rob
 
when you did the debug on ppp did the ISP accept authentication?

sh interface your looking for errors..
..below you see interface resets and crc errors..

I think the problem may be the DHCP server portion is not supplying any DNS settings to your clients. If you try a numeric web address you will probably get there but there is nothing to resolve a name to the numeric address in place. Check the clients and see if there is a valid DNS entry in the output of ipconfig /all. If none exists the enter no import all and dns-server xxx.xxx.xxx.xxx into your DHCP statement.
