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 ! version 12.0 service timestamps debug uptime service timestamps log uptime no service password-encryption ! hostname Router ! enable secret 5 $1$K.Ac$8VHFnPMHi2TuvTcZF.NAC/ ! ip subnet-zero ip name-server 202.0.62.1 ! ! ! interface Ethernet0 ip address 172.16.1.16 255.255.0.0 secondary ip address 192.168.1.16 255.255.255.0 ip directed-broadcast ip nat inside ! interface Ethernet1 ip address 202.0.62.4 255.255.0.0 ip directed-broadcast ip nat outside ! router rip network 172.16.0.0 network 192.168.1.0 network 202.0.64.0 ! ip classless ! ! line con 0 transport input none line vty 0 4 password cisco login ! end

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.

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,

Grant said the following on 4/05/2008 5:24 AM:

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?
