Please help redirecting locally generated traffic

I have a situation where an application on my box wants to
talk to the
wrong IP address.  The developers will gladly fix the bug in
the next
version but I need a quicker fix.

Here is the situation.  I have traffic that is going to
10.0.0.1 and needs
to got to 198.162.0.1.  It's created on the machine that I
need to do the
routing on.  It's a Linux machine using iptables 1.2.9. 
Neither SNAT or
DNAT seem to work.  DNAT wants to work on the incomming
packets but does
what I need.  SNAT will work on the outgoing packets but
doesn't do what I
need.  Mangle seems to only want to send packets to my
127.0.0.1.

Any help would be appreciated.

Will

Ugh.  You are wanting to redirect traffic that is not
following the 
normal packet flow through the kernel.

Have you considered adding the 10.0.0.1 IP address to
equipment with a 
corresponding 10.0.0.x IP address to your system?

Or you may be able to look in to some sort of (socks?) proxy
rapper that 
will bind a 10.0.0.1 and allow you to redirect the traffic
over to 
198.162.0.1.
