[f-nsp] UDP and non-DSR ?

[David Miller]

I have an application that's time sensitive enough that normal DNS timeouts won't work if one of them is down.

I have a pair of Serveriron 4G's, so it's natural to use a couple of name servers and load balance between them with a health check.  I do this to access http on load balanced web servers and it works fine - the source address becomes the SI and the packet gets NATted both ways.

Question: When doing UDP DNS queries, how do I avoid DSR?  

Thanks,
