4.0 Configuration
IP pass-through allows the WAN IP address to be assigned to the
device connected to the RJ45 LAN Port. In this mode the
IPn4G
is for
the most part transparent and forwards all traffic to the device
connected to the Ethernet port except that listed below:
The WebUI port (
Default Port:TCP 80
), this port is retained for remote
management of the IPn4G. This port can be changed to a different port
under the
System > Settings
Menu.
The SNMP Listening Port (
Default Port: UDP 161
).
Refer to the Appendix for an example of how to configure IP-Passthrough.
IP-Passthrough
Values (selection)
Disable
Ethernet
This field is only visible once IP Passthrough has been selected
above. This gives the user the option to manually configure the IP-
Passthrough feature of the modem. (It is recommended to only use
this option if you are an advanced user and the automatic settings do
not work for your application or carrier)
IP-Passthrough Mode
Values (selection)
Auto
/ Manual
This field is used to specify the Gateway to be used for IP Passthrough
if set to manual mode. As mentioned above it is recommended to use
the Auto mode for IP-Passthrough.
IP-Passthrough Gateway
Values
(no default)
This field is used to specify the Netmask to be used for IP Passthrough
if set to manual mode. As mentioned above it is recommended to use
the Auto mode for IP-Passthrough.
IP-Passthrough Netmask
Values
(no default)
This is a read only field that displays the current IP address assigned by
the cellular carrier that will be assigned (DHCP) or needs to be
configured (Static) on the attached device.
IP-Passthrough Local IP
Values (selection)
(current carrier IP to be
assigned to attached
device).
In some cases, a user may want to lock onto certain carrier to avoid
data roaming. There were four options presented to a user to choose
from, Auto, SIM based, Scan & Select and Fixed.
Auto will allow the IPn4G to pick the carrier automatically. Data roaming is
permitted.
SIM based will only allow the IPn4G to connect to the network indicated by
the SIM card used in the unit.
Manual will scan for available carriers and allow a user to select from the
available carriers. It takes 2 to 3 minutes to complete a scan.
Fixed allows a user to enter the carrier code (numerical) directly and then the
IPn4G will only connect to that carrier.
