The following table describes the labels in this screen.
4.8.1 DHCP Table
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual
clients to obtain TCP/IP configuration at start-up from a server. You can configure the ZyXEL
Device as a DHCP server or disable it. When configured as a server, the ZyXEL Device
provides the TCP/IP configuration for the clients. If DHCP service is disabled, there must be
another DHCP server, or else the computer must be manually configured.

LABEL DESCRIPTION
Destination The route applies to traffic going to this network address.
Gateway This is the router the ZyXEL Device sends traffic to in order to forward the traffic to the
destination listed in the route.
Subnet Mask This is the network number of the gateway to which this route forwards traffic.
Flag This displays more information about the route.
U - up
! -reject
G - gateway
H - host
R - reinstate
D - dynamic (redirect)
M - modified (redirect)
Metric This field sets this route's priority among the routes the ZyXEL Device uses.
The metric represents the "cost of transmission". A router determines the best route
for transmission by choosing a path with the lowest "cost". RIP routing uses hop count
as the measurement of cost, with a minimum of "1" for directly connected networks.
The number must be between "1" and "15"; a number greater than "15" means the
link is down. The smaller the number, the lower the "cost".
Service This displays what type of traffic this route is for. The field is blank when the route is
for all types of service.
Interface This route has the ZyXEL Device send traffic through this interface.
