Subject: clone packet with new destination address
Date: Fri, 22 Oct 2010 08:31:59 -0400	[thread overview]
Message-ID: <4CC1843F.8050903@earthlink.net> (raw)

Hello,

Problem:
I have a two monitoring servers behind a a linux firewall, one is 
primary and one is backup.
In the field we have units sending udp informational packet to the 
primary server. On the
linux firewall I would like to copy this packet and change the 
destination address of the copied
packet to point to the backup server. Is there a way to do this without 
writing any code?

NOTE:
Currently the firewall is FreeBSD and we accomplish this rather easily using
ipfw along with natd, but we want to move to linux for our firewall.

Thanks for any ideas,
Steve
