4.3 Enabling/Disabling the Solid Firewall
Solid Firewall, when enabled, prevents all access from the WAN or Internet/Intranet into the small-office LAN.
Outgoing traffic from the LAN will be forwarded to the WAN. Incoming traffic from the WAN will be blocked
from entering the LAN. Only those applications that are enabled via the Firewall Forward Application List (for
example, Web browsing, FTP, email servers, etc.) will be allowed to enter the LAN. By default, the Solid Firewall
is disabled. In Single IP mode, Solid Firewall is always enabled by default and cannot be disabled.
To enable the Solid Firewall feature (in regular router mode):
1. From the Main menu, select option 2, Security Setup.
2. From the Security Setup menu, select option 3, Firewall Options.
FIREWALL options setup
Enabling FIREWALL will forward outgoing sessions
from LAN to WAN and block incoming sessions from
entering the LAN except for applications that are
enabled by the FIREWALL FORWARD APPLICATION LIST.
