Figure 34-41. Configuration > Outbound Proxy page FTP tab
The Enable Active-to-Passive Translation checkbox enables TCP proxy sessions processed as
FTP to translate "Active" data transfer requests to "Passive" data transfer requests. The
"Passive" (PASV) mode is a more secure form of data transfer, allowing the FTP client to
initiate all connections. For older FTP clients that do not support PASV, enabling this option
will allow them to operate with FTP servers that require PASV.
Peers
Multiple ZoneRangers may be configured to work in concert to achieve greater management
reliability. The Configuration > Peers page is used to configure multiple ZoneRangers to work
in this environment.
Figure 34-42. Configuration > Peers page Group tab
Configuring the ZoneRanger group
On the Configuration > Peers page Group tab, the Group Name is used to filter duplicate
information from multiple ZoneRangers reporting to the same Ranger Gateway. Redundant
ZoneRangers always have the same group name. You can give multiple nonredundant
ZoneRangers the same group name if they cannot become redundant, but filtering of duplicate
information is still desired.
Configuring redundancy
Redundancy links two or more ZoneRangers so that services can be provided continuously,
even if one of the ZoneRangers become unavailable. Redundant ZoneRangers share
configuration information and database information. The Configuration > Peers page
Redundancy tab is used to establish redundant ZoneRangers.
