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 requires a reboot.
This command sets Ethernet Firewall Filtering ON or OFF and allows you to list the active state.
Note:
To perform Firewall Filtering, IP routing must be enabled.
on Sets firewall filtering on. IP routing must
also be enabled for filtering to be performed.
off Sets firewall filtering off.
list Lists the current status of firewall filtering.
Example:
eth ip firewall list
Response: The Internet firewall filter is currently on.
0 offending packets were filtered out.
