Trying to understand why PAT isnt working.

Hello /r/networking,

I am a college student who is just trying to learn basic Cisco router and switch configuration. One of the labs has a cisco 2900 series router and I am attempting to setup PAT in accordance with this video([CBT Micro Nugget on PAT]https://www.youtube.com/watch?v=rymxrGyiUp8) I was sure to set up the IPs on the 2 interfaces beforehand and I followed the videos instructions to the letter but when I attempted to ping the outside world from the computer on the LAN it kept saying that destination was unreachable.

Below is my configuration

interface Embedded-Service-Engine0/0

no ip address

shutdown

!

interface GigabitEthernet0/0

ip address 192.168.1.1 255.255.255.0

ip nat inside

ip virtual-reassembly in

duplex auto

speed auto

!

interface GigabitEthernet0/1

ip address 10.10.10.106 255.255.255.0

ip nat outside

ip virtual-reassembly in

duplex auto

speed auto

!

interface GigabitEthernet0/2

no ip address

shutdown

duplex auto

speed auto

!

!

ip forward-protocol nd

!

no ip http server

no ip http secure-server

!

ip nat inside source list NAT_THIS interface GigabitEthernet0/1 overload

!

ip access-list standard NAT_THIS

permit 192.168.1.0 0.0.0.255

Note. I have port GE0/0 connected directly to the nic of a computer. The Configuration of the computer is

192.168.1.5/24 and the gateway is set to 192.168.1.1

One of the things that caught my eye was when I saw that I can't even ping from the router CLI

Any help would gladly be appreciated

If im missing any part of the config in this post, let me know and I will update the post
