MTU
–The largest amount of data that can be transferred across a
given physical network. Ethernet limits transfers to
1500
octets of
data. Normally, you should leave this value at its default value.
Change it only if the ISP is providing a MTU that is not optimal
Connection Health
Check
•
Method
–
ICMP:
The health check is performed by sending an
ICMP echo request
packet to the specific destination.
The specific destination ("Alive Indicator") could be either:
1. If the input box is filled (NAME or IP address): the host is
used.
2. If the input box is left blank: gateway of WAN interface will
be used. Then if one ICMP echo reply packet from Alive
Indicator or gateway is received, the connection is
considered OK. If there is no response received after 4
tries, the connection is considered as failed.
HTTP:
The device gets TCP connection with the Alive Indicator
first. Then the device sends
HTTP HEAD
packet to the Alive
Indicator. If any HTTP DATA from the Alive Indicator is
received, the connection is considered OK. If there are no
response received after 5 tries, the connection is considered
as failed.
Traffic
:
If there is no traffic on the WAN port in the Interval
time, the connection is considered as failed
•
Interval
– The period to check if the WAN port is alive or not.
•
Alive Indicator
– This is used for the ICMP or HTTP Method to
determine if your Internet connection is active or not. (You can enter
either the IP address or host name
Transparent Bridge
Option
•
Bridge Mode
– If Set to Enable, traffic from Lan hosts with real IPs
can go through the specific WAN port without NAT translation. This
device works like a bridge switch for that specific WAN port.
•
NetBIOS Broadcast
– If enabled, NetBIOS Broadcast packets are
allowed to pass through the device
