Connecting the Server to the Ethernet
The 10/100 Ethernet interfaces directly support 100BaseTx or 10BaseT twisted-pair Ethernet.
The actual hardware is not numbered by slot. The slot numbers are provided in Figure 11 for
your reference.
Because slots 1, 3, 5 and 7 have IPSec-only interfaces (meaning they will only handle IPSec
packets and will drop all other traffic), you need to pay special attention to your Ethernet
connection setup.
The IPSec-only slots should be used only if you are planning to set the IntraPort-8 to operate in
parallel with your existing firewall. In this setup, the Ethernet interfaces on slots 1, 3, 5 and 7
can be connected to the same Ethernet segment as your Internet gateway router. The Ethernet
interfaces on slots 0, 2, 4 and 6 serve as IP, IPX and AppleTalk router ports for your internal
networks.
The other option is to set up the server behind your firewall using the Ethernet interfaces on
slots 0, 2, 4, and 6 only. In this scenario, the other slots are not used You will also have to set up
your firewall to allow IPSec traffic through.
If your twisted-pair hub is already in place, you can connect an interface to an active network
without interrupting network activity.
Simply plug an unshielded twisted-pair cable (that is already connected to your
10BaseT-compatible or 100BaseTx-compatible twisted-pair hub) into the RJ-45 Ethernet
connector on the back of the unit.
