IP Routing Question

[coxit]

I need some help on finding out what "ip route" statement I need to add to my Cisco 4000 router.

I currently have my 4007 router connected to the Internet via CM on Ethernet 0 with the IP of 68.105.X.X. On ethernet 1 (10.10.10.1) it is connected to a Cisco 4006 switch. The only route I have currently in place is 0.0.0.0 0.0.0.0 68.105.207.1. I can ping internet addresses from the router, however when I try to ping internet addys from the switch it fails. When I do a traceroute from the 4006 switch to say google IP the only hop i get is the router eth1 interface (10.10.10.1) and then it fails after that. Of course I am able to ping both eth 0 and eth 1 of the router from the switch but thats it.

Any help would be appreciated. Thanks

Sounds more like you need a gateway setting in the switch actually.

Take Care

If at first you don't succeed, skydiving is not for you.

What should i make the gateway to be. The router interface 10.10.10.1 or the port connected to the cable modem which holds the IP od 68.105.207.27?

Here is the config on the switch:

!

#module 4 empty
!
#module 5 empty

end


And on the router:

interface Ethernet0
description WAN COnnection
ip address 68.105.207.27 255.255.255.224
no ip directed-broadcast
no ip route-cache
no ip mroute-cache

!
interface Ethernet1
description To 4006 Switch

!
interface Ethernet2

!
interface Ethernet3

no ip address

no ip route-cache
no ip mroute-cache
!
interface Serial2
no ip address

no ip route-cache
no ip mroute-cache
!
ip classless
ip route 0.0.0.0 0.0.0.0 68.105.207.1
!

ETH0 is my connection to the Internet and ETH1 is connected to the 4006 switch.

Right-on Burt as usual. Also as Matt pointed out,
and the OP isn't clear, if trying to ping from the
switch console,

ip default-gateway 10.10.10.1

But this only affects the switch itself, not any
devices connected to it.
