It can be that your Firewall is blocking access, disabling Firewall, and try connecting. If still, you get similar issue then,

1. Goto FileZilla Menu : Edit -> Settings ( FileZilla -> Settings on Mac OS X)
2. Select : Connection -> FTP -> Active Mode : Ask your operating system for the external IP address
3. Select : Connection -> FTP -> Passive Mode : Fall back to active mode
4. Click OK!
5. Try connecting to the server.
