Multiple IP addresses for FTP

Hi everyone,


I was wondering if you could provide me with some
background on this one. I am trying to setup a small
hosting company. I have used host headers to allow access
to the various www sites and that works great, but I
cannot for the life of me figure ot how I can do the same
for ftp site. I have tried using virtual directories and
this works fine if I give everybody the same ftp address
and then get windows to redirect them to the right folder
according to their user name and password. But what I am
trying to achieve is to allow each customer to connect to
ftp://theirsite.com and not through one generic one. Is
there a way for this to be done without using a unique IP
address for each ftp site? If not do I need a special
kind of router (for example only specific Cisco models)
or can I do this with any old firewalled ADSL router? It
does seem as a fairly expensive way to go abou it
(assigning unique public IP addresses), so is this how
ISP's are doing it? Thank you very much for your help.

Hello,

There are two ways you can do this depending on which version of IIS
you are using.

In IIS6 (Windows 2003) you can configure an Isolated FTP site which
keeps users' directories separate from each other.

In IIS5 (Windows 2000) you can configure users' home folders which
provides a form of isolation but isn't as intuitive as the new method
in IIS6. However, I've used the IIS5 method to host literally hundreds
of user's web sites on IIS5 servers and it does work well if properly
implemented.

Both methods require only one public IP address because you are using
only one FTP site with virtual directories and not multiple FTP sites.
There is no host headers functionality in <a style='text-decoration: underline;' href="http://FTP." target="_blank">FTP.</a> To host multiple FTP
sites on one IP address you would have to use different ports for each
one - obviously yo can see the support issues this is going to cause
you....
