setting up network with cisco router and alcatel adsl router

Hi all,

I try to set up a network. One network is a 192.168.1.0 network. Through the cisco 1603 router I try to route the clients from that network to the internet (through alcatel adsl router with ip of 10.0.0.138).

As I am quite new to this material, can someone tell me how to do that? I have added a gateway of 10.0.0.138 to the e0 interface (e0 has two ip addresses: 192.168.1.254 and 10.0.0.254). I can't even ping from the 192.168.1.0 network to 10.0.0.138... And that with the fact that pings from clients in the 192.168.1.0 network reach clients to the 10.0.0.0 network I have set up also.....

What am I missing?

Many thanks,

Koelie

Dear Koelie,

Your equipment is clearly not suited for this setup. You are trying to set up two IP networks on the same cable and enable routing between them. This will not work by just assigning two differnet IP adresses to one interface.

You need a router with two ethernet interfaces to do this.

If you like, please check the IOS docs about interface configuration for IP.

Hi lgijssel,

The e0 interface has two ip adresses: 192.168.1.254 and 10.0.0.254. By that I can ping from 192.168.1.100 to 10.0.0.100, so I would say routing works? But I can't ping from 192.168.1.100 to 10.0.0.138 (the DSL router). How come?

Check if the dsl router has a route to 192.168.1.0 network, otherwise packets will reach the DSL router and the DSL router will drop them

Anand,

Thanks for your reply. That idea had reached my brain also and I have tried to do that. I changed the ip.ini file on the alcatel box and the outcome is: I have no connection to my alcatel at all anymore, not even ping.... any suggestions now? ;)

So, the ping-of-life has rescued me here...pfjew! The alcatel box is up again.

Any suggestions what route add command I should add to the alcatel box? Or to the Cisco router?

In the alcatel box, add a route for 192.168.1.0 and point it to 10.0.0.254 (the e0 of Cisco router)

Could you specify what I should enter in the source, destination, gateway and metric fields?

Re: setting up network with cisco router and alcatel adsl router

OK, i figured it all out:

On the cisco router : ip route 0.0.0.0 0.0.0.0 10.0.0.138

On the alcatel box: ip route 192.168.1.0/24 10.0.0.254 metric 0

And it works!
