How do I change the FTP port in Internet Explorer and/or Windows Explorer?

First you will need to set the proper settings to allow Windows Explorer to connect to the FTP server:

1. Open control panel via your start menu and double click on Internet Options. 
   
    
   
   
   
2. Select the Advanced tab at the top and scroll down to you see Enable FTP folder view (outside of Internet Explorer) and make sure it is Checked. 
   
    
   
   
   
3. Scroll down to Use Passive FTP (for Firewall and DSL modem compatibility.) and make sure it is checked. Click OK to save these settings.
