- A jump host is a server over which traffic to and from a network is channeled, see Jump Host Architecture.
- Jump hosts can be used to provide a secure method of file transfer across network boundaries by not allowing direct transfer over the boundary.
- DMZs (demilitarized zones) are a common form of jump hosts.
- JADE can be used to carry out file transfer via a jump host, once a JADE Client has been installed on the jump host.
- Different protocols can be used for transfer between the source host and the jump host than for the transfer between the jump host and the target host. To this end, different parameter sets are defined in the JADE configuration for each part of the transfer.
The focus of this article is the configuration of individual parameters - a more general description of the considerations involved in setting up a jump host file transfer can be found in the following article:
Schematic Diagram
The following diagram shows schematically how files are sent via the Internet from one network with a DMZ to another network with a DMZ.

The XML element hierarchy for the configuration of a jump host is shown below for a Copy operation with the jump host on the target side of the operation:
...
A fragment element is specified in the usual manner and is called from a CopySourceFragmentRef or CopyTargetFragmentRef element in the Profiles branch of the configuration.
The jump host is specified as part of the configuration of the file transfer fragment using the JumpFragmentRef element, which can be specified as an optional child of all connection fragment elements, with the exception of SMBFragments.

Element Use Restrictions
Only a single JumpFragment can be specified as part of a connection fragment element.
Jump hosts cannot be specified as part of AlternativeFragment elements.
Parameter Restrictions
