I was hoping to get some suggestions on the best way to handle this. We just put a DSL line for inet backup and I'd like to have it automagically failover.
We are running OpenBSD 3.9 -stable on a box with four interfaces. Currently we have one interface connected to our private network and one interface connected to our router. I could connect the DSL router and the t-1 router directly to my firewall on two seperate interfaces and maintain two seperate pf.conf files and manually change the active interface. this isn't what I want to do but I know it will work. What are my other options? I'd like to have it automatically fail over but I'm not sure what is required to do that. Thanks, John
