I think that you are going about it the wrong way. You wont proxy to

issue
doesn't come up. And your customer always gets a response.
Well, if I get the proxy handling to function the way I am
envisioning, I effectively create a high-availability cluster with
the
proxy as my availability manager. :)
As you have seen it's not straightforward.
Second, those home servers are
incredibly cheap and easily replaceable. A high-availability cluster
probably would not be.
Ahem. It can be just as cheap, since you probably already have it.

Linux HA is a great project. If I was only dealing with a local
situation, I would consider it. My solution is going to be working
with my home servers, but also home servers beyond my control. I did
not mean to imply I am trying to implement an HA RADIUS cluster
through this discussion. I am not. It is just a side-effect of the
process.
Given what Alan's talked above, I believe I have a very small patch
that allows for more flexible handling of no-response situations.
Hopefully it will a) work and b) be palatable to the freeradius team.
