Hi
I have a 1605 , and since its got 2 ethernet ports I thought i would
like to use it in as a useful part of my network instaed of just a lab
situation.
I'm trying to configure my 1605 router as a gateway to the internet, but
not having much success.

192.168.1.0 is my primary network (172.16.1.16 secondary) and 202.0.62.4
goes to my cable modem (202.0.62.1)

Here's my running-config,
what have i missed ?,
any help please ?

Router#sh conf
Using 683 out of 7506 bytes

As far as I can see, your RIP table doesn't have a default route.....
If I'm correct you should try typing(in "configure terminal" mode):

ip route 0.0.0.0 Ethernet1

Grant,

Your NAT will not work - you did not define major part of it - IP POOL. Here
is a link on how to configure simple NAT for Cisco IOS.

http://www.cisco.com/en/US/tech/tk648/tk361/technologies_configuration_example09186a0080093f2f.shtml

Also, do a little search on Cisco website for configuration examples, for
example, how to set access lists, do static translations, limit traffic,
etc.

Good luck,

Mike

You haven't finished the NAT:
ip nat inside source list NAT_ACL interface Ethernet1 overload
!
ip access-list standard NAT_ACL
permit 192.168.1.0 0.0.0.255
permit 172.16.0.0 0.0.255.255

You also don't seem to have a default route:
ip route 0.0.0.0 0.0.0.0 202.0.62.1

Also, are you sure about that subnet mask on Ethernet 1? It seems
awfully large.

Can you ping 202.0.62.1?
