Hi,

so I conclude  the  CCP test didn't work so why did you rate the answer if it didn't solve your problem? It may be misleading for other people.

Can you ping 8.8.8.8  from router? what does CCP tells?

Regards.

Alain.

Have you got a modem or another router/modem  attached to the router ?

[cadet alain]

Looking back at your config I saw you were using fastethernet4 for WAN connectivity but this is a switch port not a routed port.

[el_moshin]

the router port 4 indicates that the WAN port and of course, there is

another router I set the ISP, is a cisco 1841, so I would like to leave the

881 as a bridge to solve the problem then

So if the broadband service is activated on the 1841 then no need for dialer commands on the 881, just put an ip address on fa4 in the same range as the 1841 interface connected to your 881.

Is really the 1841 under your control and in your premises?

Regards.

Alain.

[el_moshin]

you tell me to put the same ip range on the WAN port of 881, well if so in

the configuration by ccp express but still do nothing, ahh and 1841, it

installed the ISP

Hi,

So you have a 1841 with a modem module installed at your premises by ISP and then you want to use  a 881 linked to this 1841 and your clients are linked to switchports of this 881. Is this correct? then get rid of all the dialer stuff and just put an ip address on the interface of your 881 which connects to 1841 in the same subnet as the interface of 1841 connecting to 881. Is it clear? This should be a private address( 10.x.x.x or 172.16.x.x or 192.168.x.x).

then you must  configure a static default route pointing to the ip address of 1841 interface

Regards.

Alain.

[el_moshin]

then I configure one ethernet port 1841, a private ip to connect to the WAN

port of my 881 and then create a static route between the routers, thus

achieve Internet connection?

also should not have any settings on the 881 for my local network users access

the Internet?

Yes of course, you'll have to configure an ip address on interface vlan 1 and  put it as default-gateway on clients.

On 1841 you'll have to do NAT overload and permit the subnet of vlan1 to be NAT overloaded .

Alain.

HI!

881 is already configured to access the internet, but you know only bad

thing is that it works if you create NAT ip pc ip you want to output the

(public) and I can do to get out all my local network for that ip

designated public Internet access?, I hope your help, thank you very

much

Greetings
