I'm guessing you have the two network cards configured on the same network, because you talk about redundancy and possibly using the same IP for both cards. I think this is where your problem lies. Unless you use some specialised software and a switch that supports it, you cannot have both cards on the same IP address (AFAIK!). Furthermore, having them both on the same network subnet will lead to problems with routing of outbound traffic from the box. For the moment I think you will have to keep one card off until someone wiser than me can suggest software which will enable what you are after. The manual alternative is to write a script to configure and "up" the second interface if the first should die. You could even add a status check (ping another IP on the subnet that should always be up), and let this run every minute in cron to "automate" the changeover. It's crude but might help you in the mean time. Regards, Patrick O'Reilly. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
