How do I route traffic from a cell network into a regular LAN/WAN etc?

[JustNxck]

I'm new so excuse the crudeness if any with my design.

I have a barebones simple cell network here. I'm trying to route traffic from the laptop to the greater network pass the router.

I can ping the router infront the laptop but I can send a packet from the laptop to any networks past the router.

Currently using rip routing as there's not many networks. The router can ping other networks just fine behind there respective routers but not this laptop I have behind it.

Help!

Is it a routing issue? Issue with IP assignments? Network Design flaw?

Hi

 If you attach the pkt file here, it better to help. Zipp it first.

As per your description, you need to add routes .  Keep in mind that the hosts your are pinging need to know how to reply to the laptop.

here ya go, theres also an issue with the network connected to the firewall im still trying to solve as well but just focus on the cell network

Hi

 I fixed the ping from laptop connected on mobile to laptop 192.168.1.2 connected on cabling network.

The problem was on routers. The router that connect to the mobile network (router3) needs to have an static route point to the COS (Central Office Server)

ip route 172.16.0.0 255.255.0.0. 192.168.3.2

This way, when someone tries to reach the mobile network, it knows that it must send to the COS.

But, the Router3 also need to inform others router that it is the entry point to 172.16.0.0 network so that everyone knows where to send the packet.

For that, you need to redistribute the static route you created:

router rip

version 2

redistribute static

Now, all router speaking RIP knows that the network 172.16.0.0 can be found on Router 3.

From that on, you can ping from um PC to the other.

Thank you for the explanation! Unfortunately I'm running an older version of packet tracer so I can't open it but I'll try and follow your explanation when I get back to my PC and get back to you.

Hello,

actually (and it might be a version 'thing', I am using 8.1.1.), I can reach anything from the laptop with IP address 172.16.0.100,even without adding and redistributing the static route. Odd...

I used the configs below (important parts marked in bold). I took some redundancies out of the RIP configurations...

Hard to say, well at least for me as I'm still learning the logic behind networking as to what I can and can't do. I did however clean up some  of the configs based on what showed so thank you.

[JustNxck]

So I followed your explanation and the laptop is now able to communicate with things outside the network just fine now which is great. 

But I couldn't have things communicate with the laptop on the cell network just the laptop outwards.

So I change the central office server setting to "allow external access" and it worked so far. Though I guess that wasn't in my original just putting it out there incase any other newbies come after me and see this post.

Thanks for this though!

[Flavio Miranda]

Great to hear!

 You mentioned that you had some problem with firewall as well, in case you need help, just ask.

[JustNxck]

I do still have that issue with my firewall but I figured I should probably make a new post for it which I just did actually.
