Have split a single shared webserver into three to segregate sites, and
placed them behind a Pound proxy at the original server IP.
I want to configure FTP for a few clients who use it occasionally, and I'm
wondering what alternative ways I can expose FTP on the public IP and route
the FTP connections to the correct machines.
I want to let machines from INTERNET access servers A, B, C through PROXY.
Each connection should be specific to the appropriate server of A,B,C.
INTERNET
|
|
PROXY
| | |

A B C
A proxy like TinyProxy would let me expose three ports on the external IP
and route them onto the correct webservers, but needs people to configure a
special port on their FTP connection.
Another method which comes to mind is something like a dedicated FTP server
which accesses the three WWW boxes via NFS on the private network, and that
just feels like too much complexity / risk for exposing FTP.
What other ways can this problem be solved?
