Just getting to grips with Cisco and have booked my course but I need an answer now.

I have a small test network which will mirrors a live and I need one IP range to get accrosss to another for the sole purpose of Internet access. See diagram www.rideabout.co.uk/files/NAT.jpg for basic layout.
There is a 2600 router and a 2950 switch with a DrayTek 2800 ADSL router connected to Internet.

Here is the config I put on the 2600 router from a web site I found but it doesnt appear to work, I didnt opt for pool of IP's I went for this one which NATs to NIC IP although I have tried both ways. I've ommited the other interfaces which arent in use. From the router I can ping both sides;

ip subnet-zero
!
!
no ip domain-lookup
!
isdn switch-type basic-net3
isdn voice-call-failure 0

interface FastEthernet0/0
 description Lan with internet connection
 ip address 192.168.100.3 255.255.255.0
 ip nat outside
 no ip route-cache
 no ip mroute-cache
 no keepalive
 duplex auto
 speed auto

interface FastEthernet0/1
 description LAN without internet connection
 ip address 10.10.10.1 255.0.0.0
 ip nat inside
 no ip route-cache
 no ip mroute-cache
 duplex auto
 speed auto

ip nat inside source list 7 interface FastEthernet0/0 overload
ip classless
ip http server
no ip pim bidir-enable

access-list 7 permit 10.10.10.0 0.0.0.255
dialer-list 1 protocol ip permit

You need a default route pointing to the DSL Router

ip route 0.0.0.0 0.0.0.0 192.168.100.1
