eth ip firewall
The router supports IP Internet Firewall Filtering to prevent unauthorized access to
your system and network resources from the Internet. This filter discards packets
received from the WAN that have a source IP address recognized as a local LAN
address. This command sets Ethernet Firewall Filtering on or off and allows you to list
the active state.
This command requires a
save
and
reboot
before it takes effect.
To perform Firewall Filtering, IP routing must be enabled. For more information, see
“
