I'm pretty sure I can solve the routing issues which is what that thread is
mainly about.  I was just hoping to get a solution that didn't involve opening
any additional rp_filter settings.  

Any idea why the client works fine under Fedora 16 but not under EL6?  I found
out that a number of the dependent libraries changed between EL6 and FC16 by
simply trying to install the FC16 rpm on EL6.  This goes back to my original
question about building a statically linked version with the FC16 libraries.  Or
do the differences go deeper?

Cheers,
Dave
