I think that you are going about it the wrong way. You wont proxy to pretend that home server has not gone down. How about this - instead of a group of stand-alone load-balanced home servers create a (true) high availability cluster. If your home server is always available this 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. Philip
