Hmm, well the script clears a lot of tables. Presumably the machine you're
ssh'ing from gets dropped. I've only ever tested the script by running
on the director console or when connected through an interface on the
director that the configure script isn't told about (eg ssh into eth2).

I expect/plan that the admin on the director will occur through another
interface which is not
a part of the lvs. Eventually filter rules will go into the configure script
which only allow LVS packet over the interfaces known to the
configure script.

netmask is wrong, try
209.116.71.36 255.255.255.255 209.117.71.36

you have an extra entry here, try instead
209.116.71.37 255.255.255.240 209.116.71.47
