Amir,

please share your script. Your question applies to all firewall boxes.
To catch any scenario of unresponsible boxes, your script has to test
real routing through your box from outside.

I was wondering if anyone has tested the following scenario
Say I have 2 machines omega0 and omega1.
They have ip addresses 10.0.0.2 & 10.0.0.3 (10.0.0.0/24) on fxp0 and
carp0 10.0.0.1, as well as 10.1.1.2 & 10.1.1.3 (10.1.1.0/24) on fxp1
carp1 10.1.1.1 respectively
As you can see they are on 2 different subnets and they route between
them.
My question is using carp has anyone tested the link/route redundancy as
follows?
For Example, Omega0's fxp0 fails, but its fxp1 does not, is there any
way to have carp see that fxp0 is down and switch both carp0 & carp1 to
omega1's addresses?
I am thinking I will have to write a script to get this done, but I
thought I would ask before I wrote one.
