I also have two switches one being a backup of the other. I am using STP, and possibly HSRP soon to provide the fault sensory information between the switches. Basically what I am looking to do is if one of the switches goes down STP will detect a closed path and automatically bring the other switch live. My predicament is that if either the switch or the firewall goes down the other has to be brought live without intervention by a user. The Cisco PIX's we have now will do automatic failover between two physical devices. They have identical configurations and when one is detected as dead the other will come online and all is well. Is there a way to do something similar with FreeBSD? Perhaps something that communicates through a serial port and can then activate interfaces or provide some other means of fault tolerance? thx nick ------------------------------------------ nick.evans network.engineering NextVenue, Inc. phone: (212) 909.2988 pager: (888) 642.5541 ------_=_NextPart_001_01BFF808.6A4C8610 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2//EN"> <HTML> <HEAD> <META HTTP-EQUIV=3D"Content-Type" CONTENT=3D"text/html; = charset=3Diso-8859-1"> <META NAME=3D"Generator" CONTENT=3D"MS Exchange Server version = 5.5.2652.35"> <TITLE>Fault tolerance across multiple boxes.</TITLE> </HEAD> <BODY> <P><FONT SIZE=3D2>I have a FreeBSD 4.0-R firewall box running IPFilter = with 4 interfaces (office, external, dmz, engineering networks).
