Help with Cisco 871-K9

[martinsajon]

Hi everyone! I'm having trouble with my 871 router.

My problem is the next one.

It's starts like this:

My ISP give me an address by DHCP, it is connected to a 1841 (Fe 0/1), on Fe0/0 I assign 10.22.1.1 and by DHCP on my 871, I gather the IP the router gives me.

Now, in the 871, as you can see on the attach everything's configured, I can make pings to everything unless to my computer, with the IP 10.22.2.3 and Gateway 10.22.2.1 (Vlan1). Therefore, I ping from my computer to the vlan1 (inside) and the Fe4 port (outside) -works- but I dont have access to the web. Neither I can ping 10.22.1.2 that is 1841 router.

Any ideas of what I'm doing wrong?

1841 is working perfect and it's natting the public ip into private.

Sorry, misunderstood your previous email. I am curious, what IOS version are you running on the 871?

The IOS version I'm running is: c870-advipservicesk9-mz.124-24.T

Just curious, have you switch the computer on 1841 to the 871 and and the computer on 871 to 1841 to see how they behave?

Also, have you tried another IOS software like 12.4(15)T9? This version is quite stable.
