You configure XORP as usual, and you need to do a bit of extra
work to start the FEA on a remote machine.

Please see the following email for details:
http://mailman.icsi.berkeley.edu/pipermail/xorp-users/2007-October/002134.html

Note that the example in that email is how to run static_routes on a
remote machine, but the solution is basically same for running the
FEA. A small clarification re. the instructions: the sample script
that is at the end of the above email should be named fea/xorp_fea,
and the real xorp_fea binary should be placed on the remote host.

Please let us know how it goes.
