Firewall
The SX II has a firewall function to provide protection for the IP network
and to control access between the internal router and LAN 1, LAN 2, and
the modem interfaces.
1. Choose Security > Firewall. The Firewall page opens, displaying the
existing IPTables rules.
2. Select the Enable Firewall checkbox.
3. Click OK.
Note: When you enable IP forwarding for Dual LAN units, use
IPTables rules to create policies for traffic being forwarded between
LAN interfaces
Add IPTable rules as needed. When you enable IP forwarding for
Dual LAN units, use IPTables rules to create policies for traffic being
forwarded between LAN interfaces.
These rules take effect immediately but persist permanently only
after clicking the Save button. If there is a mistake in the rules and as
a result, the appliance becomes inaccessible, this allows you to
recover from the mistake. Reboot the system. If you do not Save the
rules, you lose them in the reboot.
Rules are added using the IPTables command to the kernel.
