Now get the IP address: 

1. Go to the remote machine and logon
2. Call up the CMD prompt (Start - Run - type 'cmd.exe' and press 'OK')
3. Type' IPCONFIG' and press return

 This will show you the machine’s IP address.  Make a note of it.

 Check you are able to access this machine over the Internet:

Go to the Tutor machine and again call up the CMD prompt

- Type 'ping '  (e.g. ping 12.345.678.901) followed by 'return'

If you get a valid response back and do not receive any 'timeout' messages, then you know it is a public IP address. However, you still don't know if port 5151 is being blocked and you need to check this as follows:

1. Launch AB tutor
2. Select 'Tools' followed by 'Settings' and click on the 'Network' tab
3. Enter the full remote IP address and press the 'Add' button
4. Press 'OK' and then press the 'Find' button on the toolbar

If you connect OK then that's it! 

If you get a 'Connection refused' or a 'Connection timeout'  error message (10060 or 10061) then this means that a firewall or proxy server somewhere is blocking the connection.

You will now need to find out where this block is occurring and see if you can resolve this.  The firewall could be in your own organisation, at the level of the ISP through which you connect (e.g. in the case of Internet Filtering Services) or in the organisation of the remote machine. 

Once you are connected OK, then you can 'Rename' the IP address to something a little more friendly than the numbers.

- Right-click the mouse on the IP address in the list and select 'Rename'
- Enter the desired name for this machine and press 'OK'
