5.9.6 non-udp/tcp/icmp Lan SeSSionS.
When a LAN application that uses a protocol other than UDP, TCP, or ICMP
initiates a session to the Internet, the router's NAT can track such a session,
even though it does not recognize the protocol. This feature is useful be-
cause it enables certain applications (most importantly a single VPN connec-
tion to a remote host) without the need for an ALG.
NOTE: this feature does not apply to the DMZ host (if one is enabled). The
DMZ host always handles these kinds of sessions.
Enable. (Default: enabled). Allows single VPN connections to a remote host.
But, for multiple VPN connections, the appropriate VPN ALG must be used.
Disabling this option, however, only disables VPN if the appropriate VPN ALG
is also disabled.
5.9.7 appLication LeveL gateWaY (aLg) configuration.
Some applications require specific NAT handling. These applications are
pre-configured as supported in the NAT handling. These applications can be
enabled or disabled via the check boxes.
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 applications that use Real Time Streaming Protocol to receive streaming media from the Internet. EVDO QuickTime and Real Player are
some of the common applications using this protocol.
Windows/MSN Messenger. Supports use on LAN computers of Microsoft Windows Messenger (the Internet messaging client that ships with Micro-
soft Windows) and MSN Messenger. The SIP ALG must also be enabled when the Windows Messenger ALG is enabled. Required if you don't have
UPnP-enabled chat program.
FTP. Allows FTP clients and servers to transfer data across NAT. Refer to the
