I've set up m0n0wall on a soekris 4801 with 3 nics and I want to set it 
up so I can easily and hopefully, remotely, switch to the wan backup 
(opt1) in case the wan interface fails.

My first problem is I can't figure out how to make the m0n0wall 
interface (https) available through the opt1 static ip.  I've created a 
firewall rule to allow https (443) traffic though opt1. Do I need to 
enable Advanced Outbound Nat? If so, I'll have to make 2 rules to 
forward Lan to both Wan and Opt1?

But once I can see opt1 from the outside (and can configure m0n0wall 
remotely through it), What will I need to do to switch over when Wan 
fails? Could I simply choose to bridge opt1 with Wan and update my dns 
servers and the size of the traffic shaper pipes? (different isps and 
different bandwidths)

Anything else?

thx,
peter
