Cisco 861 WAN changed from DHCP to Static IP and now can't ping the internet.

Hello,

My old office uses Cisco 861 as a VPN router, with the WAN side setup to receive a dynamic IP assigned by Time Warner cable.  Now we switched to a new office, with TowerStream which provide 4G SLA'ed 10Mbit service with static IP, and I get a Cat 5 ethernet down from it.

So all I did, was to go my "interface FastEthernet4", and typed

ip address 173.243.123.123 255.255.255.252.

Changed speed to "speed 100" and "full-duplex" (as instructed by the ISP).

I also did "ip default-gateway 173.243.123.124", which is the default gate way assigned by the ISP.

I also typed "ip name-server 64.17.123.123" to setup the new DNS, am I doing anything wrong?  I can't even use the router to ping google, but if I connect the laptop directly to the outside line, then it works, so I know the outside line is good.

Am I not doing something right?  Why can't I connect to the internet?  I wasted several hours already trying everything in my book to trouble shoot a supposedly very simple configuration change.  Do I need to change something related to NAT when changing to Static IP?  My NAT was working just fine before when under DHCP.

Thanks for the help!

The below is my full config (some IPs changed to preserve anonymity):

It was a test lab I had and I changed the default gate address on a router, and had

to ammend the DHCP. When I done this the ubuntu box had a new IP in the correct subnet but couldn't ping

a remote router or access the internet.

From the Ubuntu box, I removed all DHCP setting and set the nic to manual and manually entered a new IP address, subnet mask and default gateway, I then applied this to the box.

I then went back in and cleared these setting so that the IP address, Subnet mask and default gateway where blank. I may have hit ok and tried to apply these, I then went back in and made sure all setting where blank set the nic to DHCP applied and all worked.

The issue was on the ubuntu box for me, it just kept hold of the old default gateway for some strange reason.

Hi,

to sniff traffic on linux bow use tcpdump.

Looking at your arp caches you haven't got the same mapping for 10.2.2.1 on linux and windows.

On windows the MAC is the MAC address of the Cisco router but on the linux box it corresponds to a netgear box.

Alain.

Can you ping 173.243.123.124 from router?

I think the problem is with default gateway: try to run these commands:

no ip default-gateway 173.243.123.124

ip route 0.0.0.0 0.0.0.0 interface fastethernet 4

After that ping some external IP address from your router.

Hi,

change

ip route 0.0.0.0 0.0.0.0 interface fastethernet 4

to

ip route 0.0.0.0 0.0.0.0 173.243.123.124

Regards.

Alain.

Wow, that worked!  Thanks!  Both:

ip route 0.0.0.0 0.0.0.0 interface fastethernet 4

and

ip route 0.0.0.0 0.0.0.0 173.243.123.124

allowed me to connect to the internet.  Is the later how you are supposed to connect to a "default gateway"? 

Now the question is, what exactly does the "ip route" command do, and why was it necessary when configuring static IP?  How come I didn't previously need it when my ISP provided dynamic IP?

Thanks both again for saving me hours of agony.

Now the question is, what exactly does the "ip route" command do

"ip route x.x.x.x m.m.m.m g.g.g.g" adds a static route (x - network address, m - network mask, g - gateway address)

"ip route 0.0.0.0 0.0.0.0 IP" adds a default static route

why was it necessary when configuring static IP?  How come I didn't previously need it when my ISP provided dynamic IP?

Before you changed the configuration from dynamic to static IP configuration, ISP's DHCP server has send you all network parameteres, including default gateway address. After you've changed to static you have to enter all parameters manually, including default gateway address.

Usually DHCP servers sends IP address, network mask, default gateway address and DNS servers but can be configured to send many more parameters.

Thanks, that was very useful information.  So basically, adding a static route to either the gate way IP or FastEthernet4 is like adding a default gateway, one of the parameters that the DHCP usually provides right?

Now I have a different problem.  So my router is now configured for static IP, and the router acts as a DHCP client to assign IP to all my servers in my subnet.  The laptops are fine, but my Ubuntu Linux box is having trouble getting a default gate way assigned automatically by the Cisco 861.

Do you know why? Here is my Ubuntu's routing table

*** When it boots up, you can see there is no default route.

root@dev-server:/home/developer# netstat -nr

Kernel IP routing table

Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface

10.2.2.0        0.0.0.0         255.255.255.0   U         0 0          0 eth0

169.254.0.0     0.0.0.0         255.255.0.0     U         0 0          0 eth0

*** After I added a default route to my subnet 10.2.2.0:

root@dev-server:/home/developer# route add default gw 10.2.2.1
root@dev-server:/home/developer# netstat -nr

Kernel IP routing table

Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface

10.2.2.0        0.0.0.0         255.255.255.0   U         0 0          0 eth0

169.254.0.0     0.0.0.0         255.255.0.0     U         0 0          0 eth0

0.0.0.0         10.2.2.1        0.0.0.0         UG        0 0          0 eth0

However, my Linux box still can't ping the internet!  This is driving me crazy.

I suspect this section of code might be the culprit.

ip dhcp pool ccp-pool1

   import all      <-- this imports the DHCP info from the ISP right?  But now the ISP doesn't give any DHCP info, this is quite useless?  Taking it out doesn't seem to improve the situation.

   network 10.2.2.0 255.255.255.0

   default-router 10.2.2.1

   dns-server 10.2.2.1

   domain-name local

?

Any help would be deeply appreciated.  Tomorrow is Monday and this is a dev server in production that our devs needs to be able to use and upload files to the internet. Thanks!

Hi,

Can you confirm your Linux Box is receiving an ip address with dhcp. type ifconfig -a and post here.

You can also do a debug ip dhcp server event on your router while renewing your lease.

Regards.

Alain.

And the Ubuntu server in question resides on 10.2.2.7:

Here is the DHCP binding that I have assigned to it.

ip dhcp pool Trac

   host 10.2.2.7 255.255.255.0

   hardware-address 1234.1234.1234

   client-name dev-server

   dns-server 10.2.2.1

!
I tried to add a default gateway of 10.2.2.1 (my router's IP) but the Linux box still refuses to ping the outside world, while my router and my windows laptops are able to connect fine.  Our Mac users have reported instability and have to restart the mac's network interface once in a while.
This leads me to believe that some of the DHCP parameters are not passed correctly to the machines in the subnet; since the router no longer receives full DHCP parameters from the ISP, and what's passed down to the subnet is all manually configured parameters.

Hi,

Is this MAC the real physical address? why did you change it? Can you try with client-identifier 0112.3412.3412.34  instead of hardware-address?

oh, because I was reluctant to post our real mac addresses on the internet, but here are the real dhcp bindings for this server:

ip dhcp pool Trac

   host 10.2.2.7 255.255.255.0

   hardware-address 0026.b989.64de

   client-name dev-server

   dns-server 10.2.2.1

   default-router 10.2.2.1

!

Hi,

So is this Linux box getting an ip address with dhcp?  ----->  ifconfig

when you  do an ifconfig down then ifconfig up and at same time issue debug ip dhcp server event on router what happens ?

if you use regular pool and not a static binding is it the same?

Regards.

Alain.

Hello,

Yes the Linux server is getting a DHCP IP correctly. Very strange.   And I did:

ip dhcp pool Trac

   host 10.2.2.7 255.255.255.0

   hardware-address 0026.b989.64de

   client-name dev-server

   dns-server 10.2.2.1

   default-router 10.2.2.1

!

Because client-identifier wasn't working for me before, I thought we only use client-identifier for windows, and hardware-address for Linux boxes.

This all has worked before in our old office where we were getting a DHCP IP from the ISP.  I didn't think switching over to static IP address would be this painful....

If I don't use the DHCP binding pool the result is this when I restart the network interface:

root@dev-server:~$ netstat -nr

ok,

so can you traceroute to an external ip like 4.2.2.2

Regards.

Alain.

Don't forget to rate helpful posts.

A small problem, the linux box doesn't have tracert installed, normally, all I need to do on Ubuntu is "aptitude install tracert", but I don't have the internet!

Let me try to see if I can get it some other way, but basically I get this error:

root@dev-server:~$ ping 4.2.2.1

PING 4.2.2.1 (4.2.2.1) 56(84) bytes of data.

From 10.2.2.1 icmp_seq=1 Destination Net Unreachable
