11.3.11 Firewall
Firewall Mode can limit access to the RLXIC-SG from the cellular network and
the Internet. Basic Firewall functions are available via AceManager.
Caution:
If you are using Firewall mode you will not be able to use AceManager remotely or Telnet
to the modem unless you are contacting the modem from one of the configured IP addresses.
Note:
Firewall mode will only prevent the RLXIC-SG modem from receiving data from those IP
addresses not on the Friends List. It cannot prevent data, such as pings, from traversing the
network to the modem which may billable traffic even though the modem does not receive the data.
