ftp No access, except entire Internet for anonymous ftp on pangea.stanford.edu. [Description and exceptions] 
ftp is used to transfer files. It is inherently insecure because it sends passwords and data over the network in clear text. The firewall permits outside ftp connections only to the anonymous ftp service on pangea.stanford.edu, which anyone in the School can use to share files with outside colleagues. If you need to serve large files from your own computer (such as a lab computer), enable a secure sftp server instead.
