FTP 7.0 introduced support for virtual host names as documented in the article
http://learn.iis.net/page. aspx/320/using-ftp-virtual-host-names/. Because of variety of compatibility
challenges, the decision was made to use the pipe sign “|” as a separator between the virtual host
name and the actual account name. To connect to an ftp site configured with virtual host name such
as ftp.contoso.com, that was sharing port 21 with some other site, one would need to type
ftp.contoso.com|ftpuser to log on successfully.

Since you have a single IP, you can use FTP virtual hosts by adding a host name to each FTP binding,
e.g. ftp.contoso.com, ftp.fabrikam.com, etc. When your FTP users log in, they just need to specify
the FTP virtual host name as part of their login, e.g. ftp.contoso.com|user1, ftp.fabrikam.com|user2,
etc. Jaroslav discussed the FTP useDomainNameAsHostName attribute in one of his blog posts,
which allows you to use a backslash (“\”) instead of a pipe (“|”) character, so you can use login
strings like ftp.contoso.com\user1, ftp.fabrikam.com\user2, etc.
