Don't sure if you can trick stock NATD into doing this, but Coyote Point Systems has a product (Equalizer) based on 2.2.8's NATD (modified of course) that does load balancing like this. They also have a demo (FreeQualizer) you can play with. www.coyotepoint.com i believe. -- Joey Miller UNIX System Administrator Inficad Communications 602.265.4423 / 888.265.4423 -----Original Message----- From: phill@cobia.gulf.net [mailto:phill@cobia.gulf.net] Sent: Monday, August 02, 1999 4:53 PM To: Troy Kittrell Cc: LutzRab@omc.net; freebsd-isp@FreeBSD.ORG Subject: Re: Loadbalance webservers I remember reading something on Microsoft's webpage on how they setup www.microsoft.com with a single IP, and had it hit several different machines. Maybe something like this could be done for your situation. You could possibly fake something like: |--------------| | www.site.com | | (public IP) | |--------------| _______________|_________________ | | | 10.0.0.1 10.0.0.2 10.0.0.3 You may be able to trick natd into doing something like this. Roundrobin DNS on a local network only? I know you can redirect natd to an internal machine for a certain port... it's not hard. There may be a certain program that does this, I cannot recall. --- Phillip Salzman phill@freebsd.org On Mon, 2 Aug 1999, Troy Kittrell wrote: > We looked at DNS load balancing but I wasn't at all thrilled with the > problems that come from other DNS servers caching the addresses.
