Interface
The two edit fields contain the NIC's IP address and subnet mask.
The check boxes enable the RARP, BOOTP, DHCP, DNS, and
Persistent DHCP protocols, which are alternate methods of
assigning IP addresses. On most networks, you want to enter a
permanent IP address and subnet mask and disable RARP,
BOOTP, and DHCP. However, if your network requires one of
these, you should clear the IP address (and possibly the subnet
mask) fields and ensure that the appropriate check box is selected.
Routing
The routing table tells the NIC which router or gateway to use to
access other subnets or hosts. In most situations, you can simply
add your router's IP address as the default router. All packets
destined for other subnets will be forwarded to the default router for
delivery to the destination host. If you have more complex routing
requirements, add static routing entries for specific hosts or
networks in the remaining Routing rows. Packets with IP addresses
that match a given Destination and Mask (from the first two fields in
a Routing row) will be routed to the router/gateway named in the
third field. Packets which do not match any of the listed
Destinations and Masks will be routed to the default router if one is
set.
