Nat Problem ?

Hi All, I have my 1605R router's outside on ether0 and inside on ether1. I have

my dsl modem connected in on outside (192.168.0.1 Modem - 192.168.0.2 Ether0). On the inside I have my 2908XL switch connected to Inside Ether1 which is dhcp the range 192.168.1.100 upwards.

On connect up, all is fine. I have 3 macs that get an IP from the given

range. However they dont get the DNS IP's sent to them, so I have had to manually type those in.

I can ping my modem on 192.168.0.1 from 192.168.1.103 with out any problems, but I cant get any internet on any of my macs.

Here is my conf !

Hello. This looks right to me... Have you tried using just a pc connected to the modem, and checked if the pc can reach the internet? That would rule out any nat problems with the router. Also you need a default route to the internet, ip route 0.0.0.0 0.0.0.0

192.168.0.1

Thanks for the reply, the modem works fine in my crappy linksys router. I did manage to access the modems control panel through my cisco, just couldnt get the web.

I will add the line:-

ip route 0.0.0.0 0.0.0.0 192.168.0.1

To my config, might make a difference.

Just got my Cisco Press CCNA Self-Study Library today :)

Thanks again
