Hardware Management Console and support element wiring options A local Hardware Management Console must be connected to its support Elements using Local Area Network (LAN) wiring. The Hardware Management Console and the support Elements both come with Dual Ethernet LAN adapters. The communication protocol (TCP/IP) used in Support Element to Hardware Management Console communication is defined for both adapters in the support elements.
v Ethernet only - one path wiring scenario This "Ethernet only" wiring scenario is intended for enterprises who currently have Ethernet installed and who do not want Token Ring wiring introduced into their environment. This wiring scenario requires that a second Ethernet be specified with the support Elements. The Ethernet features assume the use of 10/100 Mbit Ethernet facilities, requiring the use of CAT-5 Ethernet cabling. Since the Support Element Ethernet only feature includes two Ethernet adapters, there will be two Ethernet connections available. For this scenario, only the Ethernet cable connected to the Ethernet in the first (top) PCMCIA slot of the support Elements will be used. The TCP/IP protocol used in Support Element to Hardware Management Console communication is defined for both adapters in the PCMCIA slots of the support Elements. It will be necessary to connect the "top" Ethernet adapter cable to a customer supplied local hub capable of 10/100 Mbit Ethernet rates. It will be necessary to connect the Ethernet from the Hardware Management Console to either the same hub as the support Elements, or to a hub that connects to the Support Element hub. Chapter 6.

Mike, Is there a Firewall in place? When you VPN in, is your IP address being NAT'd to the IP address (sub net) that the z9 network is on?
