Enable
Override DNS
. Then check the
Override returned DNS Servers
box
and enter the IP of the DNS servers into the spaces provided.
Note:
Your 4G LTE carrier may have provided you with connection details. However, you
generally will only need to enter your provider’s APN and leave the other fields
blank. If provided a Pin Code you may need to use it to unlock the SIM card
.
Check
Apply
and a radio connection will be established with your cellular carrier.
Out-of-band access
is enabled, so the cellular modem connection is always ON
Verify the
Connection Status
in the
Statistics - Failover& Out-of-Band
tab is
shown as
Connected
. You can also check your allocated
IP address
You can measure the received signal strength
RSSI
from the
Cellular
Statistics
page on the
Status: Statistics
screen. -99 dbm to –90 dbm = Weak
Coverage, -89 dbm to – 70 dbm = Medium, -69 dbm or greater = Strong
Note:
You can also see the connection status from the WWAN LED. OFF is shown when in
reset mode or not powered. When powered, it will go ON and while searching for
service it will flash off briefly every 5sec. Once a radio connection has been
established with your cellular carrier (ie, after an APN has been properly
configured) the WWAN LED will blink at a rate proportional to traffic signal strength
detected i.e. OFF =Low, Blinking Slow = Low to Medium Blinking Fast = Medium to
High and ON=Strong
Step 5 Configure cellular routing features
The
ACM5504-5-L
is enabled by default in
cellular routing mode
. So the connection to
the carrier cellular network is always on, and IP traffic is selectively routed between the
cellular connected network and the local Ethernet network. Also
in this mode
Network
Forwarding
allows devices on the local private LAN to IP connect through to the public
network, and
IP Masquerading
(SNAT)
allows devices on the LAN to hide behind and share
the one public IP address when cellular connecting to the public network.
C
are must be taken to control access to connected devices. So
configure
Port
Forwarding
and set
Port Rules
so
external users can selectively initiate
connections to the masqueraded devices on the LAN
