Ubuntu Servers :: Unable To SSH From Outside LAN (Public IP Address)

Basically I am trying to set up my own server so that I can ssh into it from anywhere. I am able to SSH into my server when I use the LAN IP of my server but I am not able to SSH into it if I use the public IP address. I have read many threads and in my opinion I've tried almost all of the common fixes suggested. One possibility may be that my ISP has blocked port 22. I have taken this into consideration and sent them an email and I'm presently waiting for a reply. However, I highly doubt that my ISP has restricted acess to port 22. I would really like to be able to SSH into my server from anywhere.

1). I installed openssh client/server using the following commands:
Code:
sudo apt-get install openssh-client
sudo apt-get install openssh-client

2). I forwarded port 22 on my router. (see attachment for the settings)

3). I modified /etc/ssh/sshd_config such that my server has a static LAN address.
contents of sshd_config file:
Code:
# Package generated configuration file
# See the sshd_config(5) manpage for details
# What ports, IPs and protocols we listen for
Port 22
# Use these options to restrict which interfaces/protocols sshd will bind to .....
I then entered the command:
Code:
sudo /etc/init.d/ssh restart

4). I turned off the firewall using the command:
Code:
sudo ufw disable

5). Here is the output of the IP tables:
Code:
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
