The scenario is this - a group of machines
that need to be networked using NT 4.0, with cable redundant
networking. Two network cards per machine, and cables for each, and
TCP/IP as the protocol for both (no other protocols).
Note that you must have an IP address for EACH card on the
network. Install as per usual for NT networking, just note that you
have to set up your IP addresses for BOTH cards. Make sure IP
forwarding/routing is turned off in the "Protocols|TCP/IP|Routing"
tab, otherwise packets on one network can be routed through the
machine to the other network (very messy).
OK, so far so good, you should have two independent networks.
HOWEVER - the IP addresses for one network must have a different
subnet to the other ! Eg 203.19.130.XXX for one LAN, 203.19.222.XXX
for the other. You can also try using different subnet masks
instead, but this depends on the customer's networking
requirements. This can be really annoying if you are using DHCP to
allocate IP addresses, so bear this in mind when setting up the
network. |
