Routing. What am I missing???

Michael Durham · ‎01-06-2013

I can ping from Durham's PC to Sommer's PC just fine.

I can ping the Inernet from Server Switch (4.2.2.2) just fine

But I cannot ping the Interent from Office Switch or Durham's PC. What am I doing worng?

Hi Michael,

Did you try tracert and check where it is failing? Please provide the output of tracert 4.2.2.2 from working and non working switches?

Michael

Based on what you have supplied so far I would guess that the connection to the Internet is doing address translation for 10.0.0.0 but is not doing address translation for 192.168.69.0.

Can you provide some information about how this network connects to the Internet and about how address translation is configured there?

Ricahrd, I all that I know about the connection to the Internet is that my neighbor has Verizon 4G unlimited data (as do I) and he connects to a router via a game dongle. That router is on a 192.168.0.0 network. A second router is connected to that which is hwere the 10.0.0.0 network come in. I DO have his permission to connect to his network.

In fact, what our long term goal is for both of us to share our Internet connections when we a re both home. If one of us leaves and takes our phones with us, our come networks will still have Interent via the other person's data. This way should he/I need access to our home network we can still get there.

You may be asking WHY? Because there is no cable of DSL service herer.

I plan on giving hime a Cisco 3550 layer 3 switch to replace his main router once I figure everything out. But first I need to get out his network to the Internet. Once that is done, I will need to figure a way that I can get out both networks at the same time.

Richard Burts · ‎01-06-2013

Michael

The additional explanation is helpful, but not conclusive. It certainly suggests to me that his router is doing address translation for his network and not for your network. That would produce the symptoms that you suggest. Can you ask him to check on whether his router connection to the Internet would translate your addresses?

HI Michael,

Hmmmm...So the traffic get dropped at the first hope itself. Could you provide the output of "show ip route" from both switches.

Also what is the configuration looking like on 10.0.0.1?

Hope 192.168.0.1 is your internet router..

Yes 192.168.0.1 is my Internet router (neighbors that is)

I do not have access to the config of 10.0.0.1. It is just a Netgear router.

kcnajaf · ‎01-06-2013

Hi,

Your initial running configuration for Office Switch is showing

ip route 0.0.0.0 0.0.0.0 10.0.0.254

But the show ip route of same switch shows

S* 0.0.0.0/0 [1/0] via 10.0.0.1

Any idea why is this showing like this?

Regards

Najaf

Michael Durham · ‎01-06-2013

Richard,

Are you saying that since his router (192.168.0.1) is not providing me an IP it does not know the return path to my 192.168.69.0 network?

When I connect a laptop directly to the Wireless Bridge, I can get to the Internet. His 10.0.0.0 router does hav eDHCP set up on it. I did provide the laptop an IP address outside of the DHCP scope (on the same subnet) and it worked fine too.

Both of his routers are low end comapired to Cisco. The 192.168.0.1 router is a CradlePoint.

Michael Durham · ‎01-06-2013

Najaf,

My bad. I keep changinghte 0.0.0.0 route so that I can have Internet and communicate here via MY Verizon 4G netowrk. When I set it back to run the tests you requested, I entered ip route 0.0.0.0 0.0.0.0 10.0.0.1 I can change it back to 10.0.0.254 if you like.

kcnajaf · ‎01-06-2013

Hi Michael,

Yes please. Please change to 10.0.0.254 and provide the tracert output to 4.2.2.2 from Office switch.

My Final Project it to be able to sit at my PC, 192.168.69.150, and when I surf the Interent I want my Interenet access to use both my Internet and my neighbor's Internet connections at the same time. My neighbor will also have access to both Interenet connections. We will both be using C3550 layer 3 switches once I can get dual access working.

Hi,

You have your next hope configured as 10.0.0.254 and i can see this IP address is assigned to an Fas 0/7. Where is the physical link connected from Fas 0/7 going to?
