Connection Control Select Auto Re c o nne c t (a lwa ys- o n) if you do not want the connection to time out.
Select Co nne c t- o n- De m a nd if you do not want the connection up all the time and
specify an idle time-out in the Ma xim um Id le Tim e field.
Maximum Idle Time Specify the time in minutes that elapses before the LTE3301 automatically disconnects
from the service provider.
MTU Enter the MTU (Maximum Transmission Unit) of each data packet, in bytes, that can move
through the WAN connection.
NAT Select this option to turn on Network Address Translation (NAT) for this connection.
Network Monitoring Select this option to have the LTE3301 test the WAN connection by periodically sending
DNS Q ue ry to a DNS server or sending a ping (IC MP C he c king ) to either the default
gateway or the addresses you specify in the Ta rg e t1 and Ta rg e t2 fields.
Loading Check Select this option to check how many packets have been transmitted or received
through the WAN connection within a time period specified in the Che c k Inte rva l field.
Check Interval Type a number of seconds (0 to 99999) to set the time interval between checks. Allow
more time if your destination IP address handles lots of traffic.
Check Timeout Type the number of seconds (0 to 99999) for your LTE3301 to wait for a response to the
ping or DNS query before considering the check to have failed. This setting must be less
than the Che c k Inte rva l. Use a higher value in this field if your network is busy or
congested.
Latency Threshold Type a number of milliseconds (0 to 99999) for the latency threshold.
If the specified latency threshold is exceeded, the LTE3301 considers the check to have
failed and makes a new connection after (Latency Threshold * Fail Threshold) seconds.
Fail Threshold Type how many WAN connection checks can fail (0 to 99999) before the connection is
considered "down" (not connected). The LTE3301 still checks a "down" connection to
detect if it reconnects.
Target1/Target2 Select DNS1 to have the LTE3301 send a DNS query to the first DNS server address
assigned by the service provider.
Select DNS2 to have the LTE3301 send a DNS query to the second DNS server address
assigned by the service provider.
Select Ga te wa y to have the LTE3301 ping the WAN interface's default gateway IP
address.
Select O the r Ho st and enter a domain name or IP address of a reliable nearby computer
to have the LTE3301 ping that address.
Bridge Select this option to allow the computer connected to the first Ethernet LAN port to get
an individual IP address from the ISP’s DHCP server directly.
IGMP Select IG MP v1, IG MP v2, IG MP v3 or A uto to enable multicasting. This applies to traffic
routed from the WAN to the LAN.
Select Disa b le to turn off this feature. This may cause incoming traffic to be dropped or
sent to all connected network devices.
IGMP Proxy This field is available only when IGMP is enabled.
Select this option to have the LTE3301 act as an IGMP proxy on this connection. This
allows the LTE3301 to get subscribing information and maintain a joined member list for
each multicast group. It can reduce multicast traffic significantly.
