[Spread-users] need some help diagnosing and tuning

[John Schultz]

Mixing private ip's with public ip's usually doesn't work.

Spread expects that any daemon can communicate (route) to any other 
daemon in its configuration.  This is usually not the case with private 
ip's and multiple segments.  Apparently your configuration works 
partially, but the simplest thing to do would be to try alservice1 with 
a public ip (or remove it from the configuration) and see if that solves 
your problem.
