One of our customer sites has a Cisco 1800.
Its fastethernet0 port is IP unnumbered to the Dialer (81.86.79.XX) and is connected via a DSL interface to the web.
We want to put something into one of the switchports with a public IP (81.86.79.YY)in the same range as the IP Fastethernet0 has (this will be an ILO card that lives in the server - it just has a public IP)
I presume I need to put fastethernet0 and the relevant switchports in the same vlan? is this correct?
