server information (and the OX253P's WAN IP address). Use the
drop-down list box to select a DNS server IP address that the ISP
assigns in the field to the right.

UserDefined
if you have the IP address of a DNS server.
Enter the DNS server's IP address in the field to the right. If you
chose
UserDefined
, but leave the IP address set to 0.0.0.0,
UserDefined
changes to
None
after you click
Apply
. If you set a
second choice to
UserDefined
, and enter the same IP address, the
second
UserDefined
changes to
None
after you click
Apply
.
Select
None
if you do not want to configure DNS servers. You must
have another DHCP server on your LAN, or else the computers
must have their DNS server addresses manually configured. If you
do not configure a DNS server, you must know the IP address of a
computer in order to access it.
Multicast Setup
Multicast
IGMP (Internet Group Multicast Protocol) is a network-layer
protocol used to establish membership in a multicast group. The
OX253P supports both IGMP version 1 (
IGMP-v1
) and
IGMP-v2
.
Select
None
to disable it.
Windows Networking (NetBIOS over TCP/IP)
Allow between LAN
and WAN
Select this check box to forward NetBIOS packets from the LAN to
the WAN and from the WAN to the LAN. If your firewall is enabled
with the default policy set to block WAN to LAN traffic, you also
need to enable the default WAN to LAN firewall rule that forwards
NetBIOS traffic.
Clear this check box to block all NetBIOS packets going from the
LAN to the WAN and from the WAN to the LAN.
Apply
Click to save your changes.
Reset
Click to restore your previously saved settings.
