Hi
I have setup a firewall with 4 legs as follows:
* One leg goes to the router (cisco).
* Second leg goes to a switch connected to the internal network
(10.20...).
* The third and fourth legs are both for the dmz. one goes to a
switch with many dmz hosts connected to it, and the other goes
directly to an isolated dmz host (which the firewall acts as a
proxy-arp for it).
I've used woody+iptables+shorewall for this setting.
Now, since the firewall is the most critical host, I want to setup some
kind of failsafe, so even if that host dies all the traffic will go
through another host.
Since I don't even have an idea where to start, I'll appreciate any
ideas/comments/pointers to documentations, etc...
thanx
