will be redirected to a specific IP address in DMZ.

recommended unless they are servers that must be exposed to the
public network.
DMZ IP Address
If you enable DMZ, enter the IP address of the client to be placed in
this zone.
Application Level Gateway (ALG) Configuration
Different ALGs provide special handling for specific protocols or applications to allow data
of these applications to pass through an NAT-enabled router. For each protocol type, click
Enable to activate the ALG. A number of ALGs for common applications are enabled by
default.
Enable L2TP Allows multiple machines on the LAN to connect to their corporate
ALG: network using the Layer 2 Tunneling Protocol (L2TP).
Enable IPSec
Allows VPN clients to connect to their corporate network using
ALG:
IPSec. Some VPN clients support traversal of IPSec through NAT. This
Application Level Gateway (ALG) may interfere with the operation
of such VPN clients. If you are having trouble connecting with your
corporate network, try turning this ALG off. Please check with the
system administrator of your corporate network whether your VPN
client supports NAT traversal.
