Section ± - Configuration
Clicking the
Reboot
button will restart the
router. This is useful for restarting when you
are not near the router.
When the IPSec VPN ALG is enabled, LAN
computers can establish VPN connections
either with the same or with different VPN
servers. When the VPN ALG is disabled,
the ALG does not function; however, the
router allows VPN operation in a restricted
way. When the VPN ALG is disabled, LAN
computers are typically able to establish
VPN tunnels to different VPN Internet servers
but not to the same server. The advantage
of disabling the ALG is to increase VPN
performance (the ALG does not “get in the
way” of the communication). Enabling a VPN
ALG also allows incoming VPN connections
(refer to Virtual Services) to a LAN side VPN
server.
Note:
L2TP VPN connections typically use
IPSec to secure the connection. To achieve
multiple VPN pass-through in this case, the
IPSec ALG must be enabled.
If you enable this option, you are causing the router not to respond to ping commands to the public WAN IP address of
the router. Pinging public WAN IP addresses is a common method used by hackers to test whether your WAN IP address
is valid.
Select a firewall rule that controls access as needed for ping commands. If you do not see the firewall rule you need in
the list of firewall rules, go to the Advanced -> Firewall page and create a new firewall rule.
