How do I forward to NM3 using a NAT IPAddress on a Firewall?

As for forwarding to the Network Manager you need to setup Port Forwarding on your hub for FTP port 21 to go to the Network Manager. Most likely you have a utility program for the hub to do that.

In NotePad create a file call MMOS.ini. Add the line [Scala], next line entry one of the mmos.ini variables SSERVER_ReplaceRemoteFTPRootFolder= shown below, and save the file to :\Program Files\Scala\NetworkManager folder. You must restart Network Manager's network engine for the changes in the MMOS.ini to take place.

Examples

SSERVER_ReplaceRemoteFTPRootFolder = "fttp://username:password@host"
SSERVER_ReplaceRemoteFTPRootFolder = "fttp://username:password@host:21"
SSERVER_ReplaceRemoteFTPRootFolder = "fttp://%3F4f018dc4fd8f4763faca939aa96591c9981f1d89aba2a813c8d0%3F@host"

NOTE: Because of the HTML generation of this web page, and the special characters in the above examples has cause ftp to appear as fttp. This needs to be corrected to ftp in your MMOS.ini file.

The later example has the username and password encrypted. To generate a string like this will require another kludge - create a job in the INM server that uses an FTP folder - enter username and password, snip out text from XML files saved by the server).

Will only patch remote paths that are in the form of FTP strings.
Will only patch the host name, username, password, and port. Patching does not alter the relative path part of the patched FTP urls.
