Chapter 9 DMZ Screens

9.5 The DMZ Port Roles Screen
Use the
Port Roles
screen to set ports as part of the LAN, DMZ and/or WLAN interface.
See
for more information on port roles.
Ports 1~4 on the ZyWALL can be part of the LAN, DMZ or WLAN interface.
"
Do the following if you are configuring from a computer connected to a LAN,
DMZ or WLAN port and changing the port's role:
1
A port's IP address varies as its role changes, make sure your computer's IP address is in
the same subnet as the ZyWALL's LAN, DMZ or WLAN IP address.
2
Use the appropriate LAN, DMZ or WLAN IP address to access the ZyWALL.
To change your ZyWALL’s port role settings, click
NETWORK
>
DMZ
>
Port Roles
. The
screen appears as shown.
The radio buttons correspond to Ethernet ports on the front panel of the ZyWALL. On the
ZyWALL, ports 1 to 4 are all LAN ports by default.
IP Subnet Mask
Your ZyWALL will automatically calculate the subnet mask based on the IP
address that you assign. Unless you are implementing subnetting, use the subnet
mask computed by the ZyWALL.
RIP Direction
RIP (Routing Information Protocol, RFC1058 and RFC 1389) allows a router to
exchange routing information with other routers. The
RIP Direction
field controls
the sending and receiving of RIP packets. Select the RIP direction from
Both
/
In
Only
/
Out Only
/
None
. When set to
Both
or
Out Only
, the ZyWALL will broadcast
its routing table periodically. When set to
Both
or
In Only
, it will incorporate the
RIP information that it receives; when set to
None
, it will not send any RIP packets
and will ignore any RIP packets received.
RIP Version
The
RIP Version
field controls the format and the broadcasting method of the RIP
packets that the ZyWALL sends (it recognizes both formats when receiving).
RIP-
1
is universally supported but RIP-2 carries more information. RIP-1 is probably
adequate for most networks, unless you have an unusual network topology. Both
RIP-2B
and
RIP-2M
sends the routing data in RIP-2 format; the difference being
that
RIP-2B
uses subnet broadcasting while
RIP-2M
uses multicasting.
Multicasting can reduce the load on non-router machines since they generally do
not listen to the RIP multicast address and so will not receive the RIP packets.
However, if one router uses multicasting, then all routers on your network must
use multicasting, also. By default, RIP direction is set to
Both
and the Version set
to
RIP-1
.
