Our company is just starting to implement GIS 4.1 -
Perimeter server is installed in DMZ, and communicating with GIS
server on internal network.
FTP service is listening on default port of (GIS port range)32.
Can we configure GIS FTP service to allow external users to connect
to
standard ftp port 21 via the perimeter server WITHOUT negatively
affecting the native OS ftp server? Would like to leave the OS
server intact (say admins need to transfer a file for an OS patch),
but not require external users to use a non standard ftp port.
thanks....
