Cant see WAN gateway

[zkartchner]

Hello everyone, I have a cisco 3900 integrated services router. I am a little new to the cisco IOS. I am having an issue getting my LAN network to communicate with the WAN gateway. From hosts I can ping the interface IP address but not the gateway. I have used the default route command of IP route 0.0.0.0 0.0.0.0 [wan gateway from ISP] I have already set up NAT, DHCP, I just cant seem to get the internet working, the following is my config, any help would be appreciated.

Zach,

The only immediate thing that I see is that you inside interface is shut:

!

interface GigabitEthernet0/1

ip address 192.168.1.1 255.255.255.0

ip nat inside

ip virtual-reassembly in

no ip route-cache

shutdown

duplex auto

speed auto

Type in:

int g0/1

no shut

See if that helps..

HTH,
John

Yes I turned that on. But from the cisco IOS i cant even ping the WAN gateway of 24.249.274.145 any thoughts?

[John Blakley]

You'll need to be able to do that first. Is the interface up/up? Do you have the correct addressing from the provider?

Hey

use this

no ip route 0.0.0.0 0.0.0.0 24.249.174.145

ip route 0.0.0.0 0.0.0.0 GigabitEthernet0/0

Well its owesome man

no ip routing

enable ip routing  using

Hi,

yes turning ip routing on is indeed the solution but not changing the static route to point out a multipoint interface because it wouldn't be working if the gateway had proxy-arp disabled and it is not recommended to do so for performance.

While I agree with everyone else on enabling routing, this would solve the natting issue. The OP stated that he couldn't ping the gateway from the router which doesn't require routing since it's a connected subnet. So, if the original problem of not being able to hit the gateway from the router is resolved then enabling routing will fix the natting issue but it will not fix the originally stated problem.

Thanks John. So knowing this after I have enabled IP routing what is the next step to getting the internet working for my LAN users? My ultimate goal is to just get the internet working...

Thanks!

Thanks I did that but now where do input the default gateway of 24.249.174.145 from my ISP so I can get the internet working on my LAN? I still can't ping it.

Hi,

leave the old static default route: ip route 0.0.0.0 0.0.0.0 24.249.174.145

and try pinging 8.8.8.8 from the router, maybe the ISP is filtering pings.
