Re: DBU oddity

[Charles Wilt <charles.wilt@xxxxxxxxx>]

The default behavior of DBU requires a confirmation to change or
delete a record...

In other words, you end up having to press enter twice.  Perhaps you
missed doing the second and thus the record was not changed.

The corporate office wants all the hospitals in the system to convert to a 10.x.x.x addressing method.  Since all the locations use NAT to connect to the private network and then through the corporate office to the outside world, that doesn't make sense to me.  Is there any rationale for changing addressing behind a NAT firewall?
