DMZ IP Address:
Specify the IP address of the computer on the LAN that you want to
have unrestricted Internet communication. If this computer obtains
it's IP address automatically using DHCP, be sure to make a static
reservation on the Setup > Network Settings page so that the IP
address of the DMZ machine does not change.
PPTP: Allows multiple machines on the LAN to connect to their corporate
network using PPTP protocol.
IPSEC (VPN):
Allows multiple VPN clients to connect to their corporate network
using IPSec. Some VPN clients support traversal of IPSec through
NAT. This 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.
RTSP: Allows application that uses Real Time Streaming Protocol to receive
streaming media from the Internet. QuickTime and Real Player are
some of the common applications using this protocol.
SIP: Allows devices and applications using VoIP (Voice over IP) to
communicate across NAT. Some VoIP applications and devices have
the ability to discover NAT devices and work around them. This ALG
may interfere with the operation of such devices. If you are having
trouble making VoIP calls, try turning this ALG off.
