X-BeenThere: freebsd-questions@freebsd.org X-Mailman-Version: 2.1.1 Precedence: list List-Id: User questions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 09 Jul 2004 13:14:23 -0000 I'd like to implement some style of load balancing for my smtp and spamassassin servers. It was suggested to me that layer-4 switching was the way to go. I do not want to do round-robin DNS, as it could prove to be a problem if one of the boxes goes down. For bridging type firewalls and/or network surveylance equipment, I often put 5 NIC's into a FBSD box and it works perfectly great. I'd like to know if FBSD is capable of layer-4 switching, or some other similar technology to load balance that it can do while loaded up with NIC's. Tks for any input, suggestions or advice. Cheers, Steve
