a single ip adress. I send you my asa config offlist. But the ASA is
currently offline and it took the first, second, third ip address of the
specified range and used it. My ASA is still offline and I'm still 3000
KMs apart. But on Sunday I'll probably drive to the computing center and
hook it back up.
Note: The ASA can assign IPv6 addresses to clients, the IOS routers can
not.
