Special Applications

The Special Application section is used to open single or multiple ports on your router when the router senses data sent to the Internet on a ‘trigger’ port or port range. Special Applications rules apply to all computers on your internal network.

Application Level Gateway (ALG) Configurations

Here you can enable or disable ALG’s. Some protocols and applications require special handling of the IP payload to make them work with network address translation (NAT). Each ALG provides special handling for a specific protocol or application. A number of ALGs for common applications are enabled by default.

Using the Configuration Interface

PPTP:

IPSec VPN:

RTSP:

FTP:

NetMeeting:

SIP:

MMS:

L2TP:

Allows multiple machines on the LAN to connect to their corporate network using PPTP protocol.

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 adminstrator of your corporate network whether your VPN client supports NAT traversal.

Allows applications that use Real Time Streaming Protocol to receive streaming media from the internet. QuickTime and Real Player are some of the common applications using this protocol.

Allows FTP clients and servers to transfer data across NAT. Refer to the Advanced -> Virtual Server page if you want to host an FTP server.

Allows Microsoft NetMeeting clients to communicate across NAT. Note that if you want your buddies to call you, you should also set up a virtual server for NetMeeting. Refer to the Advanced -> Virtual Server page for information on how to set up a virtual server.

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.
