Note: Firewall mode will only prevent the RLXIC-EV 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 be billable traffic even though the modem does not receive the
data.
Tip: ATF? will return a list of all the current Fn settings.
5.9.6 Trusted IPs - Outbound
Trusted IPs-Outbound restricts LAN access to the external network, i.e. the
Internet.
When enabled, only packets with the destination IP addresses matching those in
the list of trusted hosts will be routed from the LAN to the external location.
Note: Outbound restrictions do not apply to responses to inbound data requests. To restrict
inbound access, you need to set the applicable inbound filter.
