Reply #3: The Cisco is a DSL Modem/Router, it should therefore route. [View All]

It seems to require a separate hub to handle multiple machines,
hence you seem to have got a second router with a built in hub.
I'm using guess and google here, but that's what I'm guessing.

You don't need it to do NAT, only the LinkSys needs to do NAT.
I don't have the manuals, I have different hardware, and I would
not touch a Cisco with a pole unless forced to, but nevertheless
I can tell you that all the Cisco needs to do is forward traffic
both ways.

The hardware I have provides web pages accessible via

http://172.16.0.254 (DSL Modem)

and

http://192.168.0.1 (Dlink Router/Hub)

And these allow all configuration to be done as I stated. The
678 seems to use a text mode configuration interface. It would seem
you just type enable/disable nat to turn it on/off, set up DHCP,
etc. I would guess from the dialog so far that you have routing
issues and the NAT works around them, but that's just a guess.
