I have two routers:

First one, connected to the DSL line directly, a huawei HG532ci, it gives me access to the internet correctly to any computer by simply connection an ethernet cable to any of its 4 ports (or wireless as well).

I have another cisco router (cisco WRT120N) i want to connect to the fist one, and connect another computer to this second router (i have my reasons to do this, and not connecting directl to the first one).

So i want the second router (cisco) to give access to the internet with its ports, just like the first one.

I connected the second router (cisco) to the first one, from a LAN2 port in the first router to the "internet" port in the second, that receives the signal, as you see in the picture below.

The first (huawei) router, settings are as follows: see picture huawei.jpg

And the cisco router settins are also in the next pictures.

Whan am i doing wrong? Cisco IP is 192.168.1.2, Huawei router IP is the same but .1, dhcp is enabled, etc... I have no i idea what setting should be whats causing the cisco router not givin internet access

I have also attached an IPconfig from the computer connected to the cisco router.

thank you!!

It sounds like you just want to use the Cisco router as a switch to get more network ports.  If this is the case, then you will want to disable all DHCP services on the Cisco and connect the LAN ports of the two routers.  If you are trying to segment a section of your network behind the Cisco router, then you will need to choose separate IP ranges for the two networks, in order for the Cisco router to properly NAT.  If I am completely off on what you are trying to do, then you may want to provide a little more information as to why you are adding the cisco into the mix. Then we can figure out how it should be setup.

Yeah, so in the cisco router, disable DHCP, the IP address that you have, (.2) should be fine.  If you want, make sure that the DNS and gateway are set to the other router (.1), then connect the other router lan2 to port 1 on the cisco and you should be off and running.  You won't be using any of the features of the Cisco router, but even using the wireless from the Cisco router will likely work as expected.  There is a chance that the wireless won't want to work properly, but I haven't seen that in a a Cisco/Linksys router in quite some time.
