Chapter 10 Network Address Translation (NAT) Screens
149
The following table describes the fields in this screen.
10.6.2 SIP ALG
Some NAT routers may include a SIP Application Layer Gateway (ALG). A SIP ALG allows
SIP calls to pass through NAT by examining and translating IP addresses embedded in the
data stream. When the ZyXEL Device registers with the SIP register server, the SIP ALG
translates the ZyXEL Device’s private IP address inside the SIP data stream to a public IP
address. You do not need to use STUN or an outbound proxy if your ZyXEL Device is behind
a SIP ALG.
Use this screen to enable and disable the SIP (VoIP) ALG in the ZyXEL Device. To access
this screen, click
Network > NAT > ALG
.

Edit Address Mapping Rule
LABEL
DESCRIPTION
Type
Choose the port mapping type from one of the following.
•
One-to-One
: One-to-One mode maps one local IP address to one global IP
address. Note that port numbers do not change for One-to-one NAT mapping
type.
•
Many-to-One
: Many-to-One mode maps multiple local IP addresses to one
global IP address. This is equivalent to SUA (i.e., PAT, port address translation),
ZyXEL's Single User Account feature that previous ZyXEL routers supported
only.
•
Many-to-Many Overload
: Many-to-Many Overload mode maps multiple local IP
addresses to shared global IP addresses.
•
Many-to-Many No Overload
: Many-to-Many No Overload mode maps each
local IP address to unique global IP addresses.
•
Server
: This type allows you to specify inside servers of different services behind
the NAT to be accessible to the outside world.
