We have new a server running HyperV with an SBS and SQL server.
Using our old server we used to run a small application which would connect to various external FTP hosts and download backups of websites.
If I run this application on our new server it seems it cannot access any of the sites, which makes me think it is being blocked.
So, how do I enable the ports (20 & 21 I think?) and can I enable them in such a way as to only allow this one application to connect and download data?
I don't want to allow FTP access to our server itself.
Is this a bad idea?
