Network Configuration
Interface
The two edit fields contain the Ethernet Interface's IP address and
subnet mask. The check boxes enable the RARP, BOOTP, and
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 Ethernet Interface 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.
