18.3  ALG Technical Reference

Here is more detailed information about the Application Layer Gateway.

ALG

Some applications cannot operate through NAT (are NAT un-friendly) because 
they embed IP addresses and port numbers in their packets’ data payload. The 
ZyWALL examines and uses IP address and port number information embedded in 
the VoIP traffic’s data stream. When a device behind the ZyWALL uses an 
application for which the ZyWALL has VoIP pass through enabled, the ZyWALL 
translates the device’s private IP address inside the data stream to a public IP 
address. It also records session port numbers and allows the related sessions to 
go through the firewall so the application’s traffic can come in from the WAN to 
the LAN. 

ALG and Trunks

If you send your ALG-managed traffic through an interface trunk and all of the 
interfaces are set to active, you can configure routing policies to specify which 
interface the ALG-managed traffic uses.

You could also have a trunk with one interface set to active and a second interface 
set to passive. The ZyWALL does not automatically change ALG-managed 
connections to the second (passive) interface when the active interface’s 
connection goes down. When the active interface’s connection fails, the client 
needs to re-initialize the connection through the second interface (that was set to 
passive) in order to have the connection go through the second interface. VoIP 
clients usually re-register automatically at set intervals or the users can manually 
force them to re-register.

FTP

File Transfer Protocol (FTP) is an Internet file transfer service that operates on the 
Internet and over TCP/IP networks. A system running the FTP server accepts 

Additional FTP 
Signaling port  
for 
transformations

If you are also using FTP on an additional TCP port number, enter it 
here.
