ZyWALL USG 50-H User’s Guide

• The SIP ALG allows UDP packets with a specified port destination to pass through.

• The ZyWALL allows SIP audio connections.

• You do not need to use STUN (Simple Traversal of User Datagram Protocol (UDP) 

through Network Address Translators) for VoIP devices behind the ZyWALL when you 
enable the SIP ALG.

Peer-to-Peer Calls and the ZyWALL

The ZyWALL ALG can allow peer-to-peer VoIP calls for both H.323 and SIP. You must 
configure the firewall and virtual server (port forwarding) to allow incoming (peer-to-peer) 
calls from the WAN to a private IP address on the LAN (or DMZ). 

VoIP Calls from the WAN with Multiple Outgoing Calls

When you configure the firewall and virtual server (port forwarding) to allow calls from the 
WAN to a specific IP address on the LAN, you can also use policy routing to have H.323 (or 
SIP) calls from other LAN or DMZ IP addresses go out through a different WAN IP address. 
The policy routing lets the ZyWALL correctly forward the return traffic for the calls initiated 
from the LAN IP addresses. 

For example, you configure the firewall and virtual server to allow LAN IP address 

A

 to 

receive calls from the Internet through WAN IP address 

1

. You also use a policy route to have 

LAN IP address 

A 

make calls out through WAN IP address 

1

. Configure another policy route 

to have H.323 (or SIP) calls from LAN IP addresses 

B

 and 

C

 go out through WAN IP address 

2

. Even though only LAN IP address 

A 

can receive incoming calls from the Internet, LAN IP 

addresses 

B

 and 

C

 can still make calls out to the Internet. 

Figure 212   

VoIP Calls from the WAN with Multiple Outgoing Calls

VoIP with Multiple WAN IP Addresses

With multiple WAN IP addresses on the ZyWALL, you can configure different firewall and 
virtual server (port forwarding) rules to allow incoming calls from each WAN IP address to go 
to a specific IP address on the LAN (or DMZ). Use policy routing to have the H.323 (or SIP) 
calls from each of those LAN or DMZ IP addresses go out through the same WAN IP address 
that calls come in on. The policy routing lets the ZyWALL correctly forward the return traffic 
for the calls initiated from the LAN IP addresses.
