LABEL DESCRIPTION
DMZ TCP/IP
IP Address Type the IP address of your ZyXEL Device’s DMZ port in dotted decimal notation.
Note: Make sure the IP addresses of the LAN, WAN and DMZ are
on separate subnets.
IP Subnet Mask The subnet mask specifies the network number portion of an IP address. Your
ZyXEL Device 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 ZyXEL Device 255.255.255.0.
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 ZyXEL Device 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. Both is the default.
RIP Version The RIP Version field controls the format and the broadcasting method of the
RIP packets that the ZyXEL Device 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.
