We are trying to move all of our 6.5 servers from public ip addresses
to private ones. the main problem is that I still need the public
addresses to work for couple of months yet. Adding a second nic bound
to the internal subnet works for some of the servers, but some of them
seem to want to only connect to the internal address. On the ones
that seem to be happy, I can ping both internal and external addresses
from annother 'happy" server. others will only grab one address or
the other (usually the internal one).

Any direction would be appreciated.
