Cisco C1117 - 4G setup

Hi, 

I am new to networking, and I am trying to setup a simple config for a Cisco C1117 to work over cellular network, but I am having issues with getting internet access, I can ping IP's but not the names from the router and when my laptop is connected, and I am not sure what I am missing from the DNS side of things?

I am using Cellular0/2/0 as the interface with the SIM, and connecting my laptop to g0/1/0

 

Any ideas, config below

If you looking to resolve from your Router you need to add the below command :

 

(config)#ip domain lookup

 

Also to make it neat you do not need both NAT config- you can use any of them as below :

 

ip nat inside source list 1 interface Cellular0/2/0 overload
no ip nat inside source list 197 interface Cellular0/2/0 overload

Rather any - i go granular for internal subnet as below :

no access-list 1 permit any

access-list 1 permit 192.168.1.0 0.0.0.255 any

This is what I get from a Ping

 

Router#ping 8.8.8.8
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 8.8.8.8, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 40/48/56 ms
Router#ping cisco.com
% Unrecognized host or address, or protocol not running.

I see a lot of this issue these day, 
I think it SP issue not your wrong config, 
anyway 
try use 
8.8.4.4 instead of 8.8.8.8 in dhcp pool and check again

Excellent, I can now ping from the router to DNS, I think it was this command, thanks

 

access-list 1 permit 192.168.1.0 0.0.0.255 any

 

now when I plug my laptop into g0/1/0, it does the same cant ping address, but can IP's, will I just need add the vlan1 to this access list 1?

Let's address 1 issue at a time, Now you can ping from Router using the DNS name,

Now the issue you have is a host is connected to Router and not able to resolve the DNS Lookup ( are you manually configuring the PC IP address -Hope so ?)

Post from the command

ipconfig /all 

or configure as below and test it.

Adding to access list 1 didn't seem to help either, what else am I missing ?

did you change the DNS server to 8.8.4.4 ??
