Cisco SDM Express doesn't work ?

Cisco router.jpg

I had the Cisco 877W Router working in my old company. The old company was closed and I bring all of network equirments to new company.

I am trying to setup this router to new company but lost menu, console cable and software CD.

What I did?

1. Reset the router to default settings.

2. Check the default network IP on router and DHCP enable automatically.

3. Open browser to and comes up Cisco SDM Express

4. Login username and password "cisco"

5. No any problem on configuation Steps - Overview, Basic Configuration, LAN IP Address and DHCP

6. After I click "Next" , it doesn't go to Internet (WAN) page. I was waiting about 30mins but doesn't go there.

I don't know what's going on. Is that anything wrong ?

Cisco SDM Express doesn't work ?


instead of connecting through sdm, telnet to the ip address of the router and type this:

-router> enable

-router# config t

-router(config)# interface fx/x  where this interface is the one with address

router(config-intf)# ip nat inside

router(config-intf) interface fx/x  where this is interface connected to WAN

router(config-intf) ip nat outside

router(config-intf) access-list 199 permit

router(config-intf) ip nat inside source list 199 interface fx/x   where this is WAN interface

Thank you Alain for quick response.

Tried it but doesn't work when type "router(config-intf)# ip nat inside"

I think the router has been reset so it has not any interface settings.

This is the router config.

Cisco Router and Security Device Manager (SDM) 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
