. IGMP (Internet Group Multicast Protocol)
is a network-layer protocol used to establish membership in a Multicast group - it
is not used to carry user data. IGMP version 2 (RFC 2236) is an improvement
over version 1 (RFC 1112) but IGMP version 1 is still in wide use. If you would
like to read more detailed information about interoperability between IGMP
version 2 and version 1, please see
sections 4 and 5 of RFC 2236
.
DHCP Setup
DHCP
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows
individual clients (workstations) to obtain TCP/IP configuration at startup from a
server. Unless you are instructed by your ISP, leave this field set to
Server
.
When configured as a server, the ZyWALL provides TCP/IP configuration for the
clients. When set as a server, fill in the
IP Pool Starting Address
and
Pool Size
fields.
Select
Relay
to have the ZyWALL forward DHCP requests to another DHCP
server. When set to
Relay
, fill in the
DHCP Server Address
field.

and from the DMZ to the WLAN. If your firewall is enabled with the default policy
set to block DMZ to WLAN traffic and WLAN to DMZ traffic, you also need to
