We wanted to have a redundant line out for web users (http proxy) in
case
the primary goes down, so we decided to make use of another line from
a
different ISP which we use for other purposes. We added another card
to
BorderManager, made it public, ran BRDCFG, and checked the filters and

exceptions. Everything looks good. Whatever filter exceptions are on
the
primary, are also on the secondary.

We went into Border Manager setup and added the second public ip
address.

How do I tell BorderManager to only use the second line when the first
one
goes down. I don't see any place for setting up metrics or the like.
In a nutshell, fault tolerance only for http proxy. I'm not concerned
with
other web access types, or for the server itself. I just want this
within
one server.

Thanks,

Lewis
